kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

ALSA: usb-audio: Stop parsing channels bits when all channels are found.

If a usb audio device sets more bits than the amount of channels it could write outside of the map array.(CVE-2024-27436)

In the Linux kernel, the following vulnerability has been resolved:

usb: gadget: f_fs: Fix race between aio_cancel() and AIO request complete

FFS based applications can utilize the aio_cancel() callback to dequeue pending USB requests submitted to the UDC. There is a scenario where the FFS application issues an AIO cancel call, while the UDC is handling a soft disconnect. For a DWC3 based implementation, the callstack looks like the following:

DWC3 Gadget                               FFS Application

dwc3_gadget_soft_disconnect() ... --> dwc3_stop_active_transfers() --> dwc3_gadget_giveback(-ESHUTDOWN) --> ffs_epfile_async_io_complete() ffs_aio_cancel() --> usb_ep_free_request() --> usb_ep_dequeue()

There is currently no locking implemented between the AIO completion handler and AIO cancel, so the issue occurs if the completion routine is running in parallel to an AIO cancel call coming from the FFS application. As the completion call frees the USB request (io_data->req) the FFS application is also referencing it for the usb_ep_dequeue() call. This can lead to accessing a stale/hanging pointer.

commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently") relocated the usb_ep_free_request() into ffs_epfile_async_io_complete(). However, in order to properly implement locking to mitigate this issue, the spinlock can't be added to ffs_epfile_async_io_complete(), as usb_ep_dequeue() (if successfully dequeuing a USB request) will call the function driver's completion handler in the same context. Hence, leading into a deadlock.

Fix this issue by moving the usb_ep_free_request() back to ffs_user_copy_worker(), and ensuring that it explicitly sets io_data->req to NULL after freeing it within the ffs->eps_lock. This resolves the race condition above, as the ffs_aio_cancel() routine will not continue attempting to dequeue a request that has already been freed, or the ffs_user_copy_work() not freeing the USB request until the AIO cancel is done referencing it.

This fix depends on commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently")(CVE-2024-36894)

In the Linux kernel, the following vulnerability has been resolved:

scsi: bfa: Ensure the copied buf is NUL terminated

Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from userspace to that buffer. Later, we use sscanf on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using sscanf. Fix this issue by using memdup_user_nul instead of memdup_user.(CVE-2024-38560)

In the Linux kernel, the following vulnerability has been resolved:

enic: Validate length of nl attributes in enic_set_vf_port

enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE is of length PORT_PROFILE_MAX and that the nl attributes IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX. These attributes are validated (in the function do_setlink in rtnetlink.c) using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation using the policy is for the max size of the attributes and not on exact size so the length of these attributes might be less than the sizes that enic_set_vf_port expects. This might cause an out of bands read access in the memcpys of the data of these attributes in enic_set_vf_port.(CVE-2024-38659)

In the Linux kernel, the following vulnerability has been resolved:

bcache: fix variable length array abuse in btree_iter

btree_iter is used in two ways: either allocated on the stack with a fixed size MAX_BSETS, or from a mempool with a dynamic size based on the specific cache set. Previously, the struct had a fixed-length array of size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized iterators, which causes UBSAN to complain.

This patch uses the same approach as in bcachefs's sort_iter and splits the iterator into a btree_iter with a flexible array member and a btree_iter_stack which embeds a btree_iter as well as a fixed-length data array.(CVE-2024-39482)

In the Linux kernel, the following vulnerability has been resolved:

drivers: core: synchronize really_probe() and dev_uevent()

Synchronize the dev->driver usage in really_probe() and dev_uevent(). These can run in different threads, what can result in the following race condition for dev->driver uninitialization:

Thread #1:

really_probe() { ... probe_failed: ... device_unbind_cleanup(dev) { ... dev->driver = NULL; // <= Failed probe sets dev->driver to NULL ... } ... }

Thread #2:

dev_uevent() { ... if (dev->driver) // If dev->driver is NULLed from really_probe() from here on, // after above check, the system crashes add_uevent_var(env, "DRIVER=%s", dev->driver->name); ... }

really_probe() holds the lock, already. So nothing needs to be done there. dev_uevent() is called with lock held, often, too. But not always. What implies that we can't add any locking in dev_uevent() itself. So fix this race by adding the lock to the non-protected path. This is the path where above race is observed:

dev_uevent+0x235/0x380 uevent_show+0x10c/0x1f0 <= Add lock here dev_attr_show+0x3a/0xa0 sysfs_kf_seq_show+0x17c/0x250 kernfs_seq_show+0x7c/0x90 seq_read_iter+0x2d7/0x940 kernfs_fop_read_iter+0xc6/0x310 vfs_read+0x5bc/0x6b0 ksys_read+0xeb/0x1b0 __x64_sys_read+0x42/0x50 x64_sys_call+0x27ad/0x2d30 do_syscall_64+0xcd/0x1d0 entry_SYSCALL_64_after_hwframe+0x77/0x7f

Similar cases are reported by syzkaller in

https://syzkaller.appspot.com/bug?extid=ffa8143439596313a85a

But these are regarding the initialization of dev->driver

dev->driver = drv;

As this switches dev->driver to non-NULL these reports can be considered to be false-positives (which should be "fixed" by this commit, as well, though).

The same issue was reported and tried to be fixed back in 2015 in

https://lore.kernel.org/lkml/1421259054-2574-1-git-send-email-a.sangwan@samsung.com/

already.(CVE-2024-39501)

In the Linux kernel, the following vulnerability has been resolved:

scsi: qedi: Fix crash while reading debugfs attribute

The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly on a __user pointer, which results into the crash.

To fix this issue, use a small local stack buffer for sprintf() and then call simple_read_from_buffer(), which in turns make the copy_to_user() call.

In nv17_tv_get_ld_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.(CVE-2024-41095)

In the Linux kernel, the following vulnerability has been resolved:

lib: objagg: Fix general protection fault

The library supports aggregation of objects into other objects only if the parent object does not have a parent itself. That is, nesting is not supported.

Aggregation happens in two cases: Without and with hints, where hints are a pre-computed recommendation on how to aggregate the provided objects.

Nesting is not possible in the first case due to a check that prevents it, but in the second case there is no check because the assumption is that nesting cannot happen when creating objects based on hints. The violation of this assumption leads to various warnings and eventually to a general protection fault 1.

Before fixing the root cause, error out when nesting happens and warn.

In the Linux kernel, the following vulnerability has been resolved:

drm/vmwgfx: Fix a deadlock in dma buf fence polling

Introduce a version of the fence ops that on release doesn't remove the fence from the pending list, and thus doesn't require a lock to fix poll->fence wait->fence unref deadlocks.

vmwgfx overwrites the wait callback to iterate over the list of all fences and update their status, to do that it holds a lock to prevent the list modifcations from other threads. The fence destroy callback both deletes the fence and removes it from the list of pending fences, for which it holds a lock.

dma buf polling cb unrefs a fence after it's been signaled: so the poll calls the wait, which signals the fences, which are being destroyed. The destruction tries to acquire the lock on the pending fences list which it can never get because it's held by the wait from which it was called.

Old bug, but not a lot of userspace apps were using dma-buf polling interfaces. Fix those, in particular this fixes KDE stalls/deadlock.(CVE-2024-43863)

In the Linux kernel, the following vulnerability has been resolved:

media: xc2028: avoid use-after-free in load_firmware_cb()

syzkaller reported use-after-free in load_firmware_cb() 1. The reason is because the module allocated a struct tuner in tuner_probe(), and then the module initialization failed, the struct tuner was released. A worker which created during module initialization accesses this struct tuner later, it caused use-after-free.

The process is as follows:

task-6504 worker_thread tuner_probe <= alloc dvb_frontend [2] ... request_firmware_nowait <= create a worker ... tuner_remove <= free dvb_frontend ... request_firmware_work_func <= the firmware is ready load_firmware_cb <= but now the dvb_frontend has been freed

To fix the issue, check the dvd_frontend in load_firmware_cb(), if it is null, report a warning and just return.

In the Linux kernel, the following vulnerability has been resolved:

netem: fix return value if duplicate enqueue fails

There is a bug in netem_enqueue() introduced by commit 5845f706388a ("net: netem: fix skb length BUG_ON in __skb_to_sgvec") that can lead to a use-after-free.

This commit made netem_enqueue() always return NET_XMIT_SUCCESS when a packet is duplicated, which can cause the parent qdisc's q.qlen to be mistakenly incremented. When this happens qlen_notify() may be skipped on the parent during destruction, leaving a dangling pointer for some classful qdiscs like DRR.

There are two ways for the bug happen:

  • If the duplicated packet is dropped by rootq->enqueue() and then the original packet is also dropped.
  • If rootq->enqueue() sends the duplicated packet to a different qdisc and the original packet is dropped.

In both cases NET_XMIT_SUCCESS is returned even though no packets are enqueued at the netem qdisc.

The fix is to defer the enqueue of the duplicate packet until after the original packet has been guaranteed to return NET_XMIT_SUCCESS.(CVE-2024-45016)

In the Linux kernel, the following vulnerability has been resolved:

fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE

copy_fd_bitmaps(new, old, count) is expected to copy the first count/BITS_PER_LONG bits from old->full_fds_bits[] and fill the rest with zeroes. What it does is copying enough words (BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest. That works fine, if all bits past the cutoff point are clear. Otherwise we are risking garbage from the last word we'd copied.

For most of the callers that is true - expand_fdtable() has count equal to old->max_fds, so there's no open descriptors past count, let alone fully occupied words in ->open_fds[], which is what bits in ->full_fds_bits[] correspond to.

The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds), which is the smallest multiple of BITS_PER_LONG that covers all opened descriptors below max_fds. In the common case (copying on fork()) max_fds is ~0U, so all opened descriptors will be below it and we are fine, by the same reasons why the call in expand_fdtable() is safe.

Unfortunately, there is a case where max_fds is less than that and where we might, indeed, end up with junk in ->full_fds_bits[] - close_range(from, to, CLOSE_RANGE_UNSHARE) with * descriptor table being currently shared * 'to' being above the current capacity of descriptor table * 'from' being just under some chunk of opened descriptors. In that case we end up with observably wrong behaviour - e.g. spawn a child with CLONE_FILES, get all descriptors in range 0..127 open, then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending up with descriptor #128, despite #64 being observably not open.

The minimally invasive fix would be to deal with that in dup_fd(). If this proves to add measurable overhead, we can go that way, but let's try to fix copy_fd_bitmaps() first.

  • new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
  • make copy_fd_bitmaps() take the bitmap size in words, rather than bits; it's 'count' argument is always a multiple of BITS_PER_LONG, so we are not losing any information, and that way we can use the same helper for all three bitmaps - compiler will see that count is a multiple of BITS_PER_LONG for the large ones, so it'll generate plain memcpy()+memset().

In the Linux kernel, the following vulnerability has been resolved:

scsi: aacraid: Fix double-free on probe failure

aac_probe_one() calls hardware-specific init functions through the aac_driver_ident::init pointer, all of which eventually call down to aac_init_adapter().

If aac_init_adapter() fails after allocating memory for aac_dev::queues, it frees the memory but does not clear that member.

After the hardware-specific init function returns an error, aac_probe_one() goes down an error path that frees the memory pointed to by aac_dev::queues, resulting.in a double-free.(CVE-2024-46673)

In the Linux kernel, the following vulnerability has been resolved:

usb: dwc3: st: fix probed platform device ref count on probe error path

The probe function never performs any paltform device allocation, thus error path "undo_platform_dev_alloc" is entirely bogus. It drops the reference count from the platform device being probed. If error path is triggered, this will lead to unbalanced device reference counts and premature release of device resources, thus possible use-after-free when releasing remaining devm-managed resources.(CVE-2024-46674)

In the Linux kernel, the following vulnerability has been resolved:

ethtool: check device is present when getting link settings

state 5 is __LINK_STATE_START (0b1) and __LINK_STATE_NOCARRIER (0b100). The device is not present, note lack of __LINK_STATE_PRESENT (0b10).

This is the same sort of panic as observed in commit 4224cfd7fb65 ("net-sysfs: add check for netdevice being present to speed_show").

There are many other callers of __ethtool_get_link_ksettings() which don't have a device presence check.

selinux,smack: don't bypass permissions check in inode_setsecctx hook

Marek Gresko reports that the root user on an NFS client is able to change the security labels on files on an NFS filesystem that is exported with root squashing enabled.

The end of the kerneldoc comment for __vfs_setxattr_noperm() states:

  • This function requires the caller to lock the inode's i_mutex before it
  • is executed. It also assumes that the caller will make the appropriate
  • permission checks.

nfsd_setattr() does do permissions checking via fh_verify() and nfsd_permission(), but those don't do all the same permissions checks that are done by security_inode_setxattr() and its related LSM hooks do.

Since nfsd_setattr() is the only consumer of security_inode_setsecctx(), simplest solution appears to be to replace the call to __vfs_setxattr_noperm() with a call to __vfs_setxattr_locked(). This fixes the above issue and has the added benefit of causing nfsd to recall conflicting delegations on a file when a client tries to change its security label.(CVE-2024-46695)

In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: Make ICC_SGI_EL1 undef in the absence of a vGICv3

On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICC_SGI_EL1 registers is trapped to EL2.

We therefore try to emulate the SGI access, only to hit a NULL pointer as no private interrupt is allocated (no GIC, remember?).

The obvious fix is to give the guest what it deserves, in the shape of a UNDEF exception.(CVE-2024-46707)

VMCI: Fix use-after-free when removing resource in vmci_resource_remove()

When removing a resource from vmci_resource_table in vmci_resource_remove(), the search is performed using the resource handle by comparing context and resource fields.

It is possible though to create two resources with different types but same handle (same context and resource fields).

When trying to remove one of the resources, vmci_resource_remove() may not remove the intended one, but the object will still be freed as in the case of the datagram type in vmci_datagram_destroy_handle(). vmci_resource_table will still hold a pointer to this freed resource leading to a use-after-free vulnerability.

binder: fix UAF caused by offsets overwrite

Binder objects are processed and copied individually into the target buffer during transactions. Any raw data in-between these objects is copied as well. However, this raw data copy lacks an out-of-bounds check. If the raw data exceeds the data section size then the copy overwrites the offsets section. This eventually triggers an error that attempts to unwind the processed objects. However, at this point the offsets used to index these objects are now corrupted.

Unwinding with corrupted offsets can result in decrements of arbitrary nodes and lead to their premature release. Other users of such nodes are left with a dangling pointer triggering a use-after-free. This issue is made evident by the following KASAN report (trimmed):

WARNING: CPU: 14 PID: 1 at drivers/pci/pci.c:4886 pci_bridge_secondary_bus_reset+0x5d/0x70 RIP: 0010:pci_bridge_secondary_bus_reset+0x5d/0x70 Call Trace: <TASK> ? __warn+0x8c/0x190 ? pci_bridge_secondary_bus_reset+0x5d/0x70 ? report_bug+0x1f8/0x200 ? handle_bug+0x3c/0x70 ? exc_invalid_op+0x18/0x70 ? asm_exc_invalid_op+0x1a/0x20 ? pci_bridge_secondary_bus_reset+0x5d/0x70 pci_reset_bus+0x1d8/0x270 vmd_probe+0x778/0xa10 pci_device_probe+0x95/0x120

Where pci_reset_bus() users are triggering unlocked secondary bus resets. Ironically pci_bus_reset(), several calls down from pci_reset_bus(), uses pci_bus_lock() before issuing the reset which locks everything but the bridge itself.

For the same motivation as adding:

bridge = pci_upstream_bridge(dev); if (bridge) pci_dev_lock(bridge);

to pci_reset_function() for the "bus" and "cxl_bus" reset cases, add pci_dev_lock() for @bus->self to pci_bus_lock().

In the Linux kernel, the following vulnerability has been resolved:

wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()

mwifiex_get_priv_by_id() returns the priv pointer corresponding to the bss_num and bss_type, but without checking if the priv is actually currently in use. Unused priv pointers do not have a wiphy attached to them which can lead to NULL pointer dereferences further down the callstack. Fix this by returning only used priv pointers which have priv->bss_mode set to something else than NL80211_IFTYPE_UNSPECIFIED.

Said NULL pointer dereference happened when an Accesspoint was started with wpa_supplicant -i mlan0 with this config:

network={ ssid="somessid" mode=2 frequency=2412 key_mgmt=WPA-PSK WPA-PSK-SHA256 proto=RSN group=CCMP pairwise=CCMP psk="12345678" }

When waiting for the AP to be established, interrupting wpa_supplicant with <ctrl-c> and starting it again this happens:

pci/hotplug/pnv_php: Fix hotplug driver crash on Powernv

The hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernel crash when we try to hot-unplug/disable the PCIe switch/bridge from the PHB.

The crash occurs because although the MSI data structure has been released during disable/hot-unplug path and it has been assigned with NULL, still during unregistration the code was again trying to explicitly disable the MSI which causes the NULL pointer dereference and kernel crash.

The patch fixes the check during unregistration path to prevent invoking pci_disable_msi/msix() since its data structure is already freed.(CVE-2024-46761)

In the Linux kernel, the following vulnerability has been resolved:

can: bcm: Remove proc entry when dev is unregistered.

syzkaller reported a warning in bcm_connect() below. [0]

The repro calls connect() to vxcan1, removes vxcan1, and calls connect() with ifindex == 0.

Calling connect() for a BCM socket allocates a proc entry. Then, bcm_sk(sk)->bound is set to 1 to prevent further connect().

However, removing the bound device resets bcm_sk(sk)->bound to 0 in bcm_notify().

The 2nd connect() tries to allocate a proc entry with the same name and sets NULL to bcm_sk(sk)->bcm_proc_read, leaking the original proc entry.

Since the proc entry is available only for connect()ed sockets, let's clean up the entry when the bound netdev is unregistered.

udf: Avoid excessive partition lengths

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: protect references to superblock parameters exposed in sysfs

The superblock buffers of nilfs2 can not only be overwritten at runtime for modifications/repairs, but they are also regularly swapped, replaced during resizing, and even abandoned when degrading to one side due to backing device issues. So, accessing them requires mutual exclusion using the reader/writer semaphore "nilfs->ns_sem".

Some sysfs attribute show methods read this superblock buffer without the necessary mutual exclusion, which can cause problems with pointer dereferencing and memory access, so fix it.(CVE-2024-46780)

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: fix missing cleanup on rollforward recovery error

In an error injection test of a routine for mount-time recovery, KASAN found a use-after-free bug.

It turned out that if data recovery was performed using partial logs created by dsync writes, but an error occurred before starting the log writer to create a recovered checkpoint, the inodes whose data had been recovered were left in the ns_dirty_files list of the nilfs object and were not freed.

Fix this issue by cleaning up inodes that have read the recovery data if the recovery routine fails midway before the log writer starts.(CVE-2024-46781)

In the Linux kernel, the following vulnerability has been resolved:

can: mcp251x: fix deadlock if an interrupt occurs during mcp251x_open

The mcp251x_hw_wake() function is called with the mpc_lock mutex held and disables the interrupt handler so that no interrupts can be processed while waking the device. If an interrupt has already occurred then waiting for the interrupt handler to complete will deadlock because it will be trying to acquire the same mutex.

Use disable_irq_nosync() instead because the interrupt handler does everything while holding the mutex so it doesn't matter if it's still running.(CVE-2024-46791)

(esw->fdb_table.legacy.vepa_fdb is null)

The bridge mode is only relevant when there are multiple functions per port. Therefore, prevent setting and getting this setting when there are no VFs.

Note that after this change, there are no settings to change on the PF interface using bridge link when there are no VFs, so the interface no longer appears in the bridge link output.(CVE-2024-46857)

  "details": "The Linux Kernel, the operating system core itself.\r\n\r\nSecurity Fix(es):\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nALSA: usb-audio: Stop parsing channels bits when all channels are found.\r\n\r\nIf a usb audio device sets more bits than the amount of channels\nit could write outside of the map array.(CVE-2024-27436)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nusb: gadget: f_fs: Fix race between aio_cancel() and AIO request complete\r\n\r\nFFS based applications can utilize the aio_cancel() callback to dequeue\npending USB requests submitted to the UDC.  There is a scenario where the\nFFS application issues an AIO cancel call, while the UDC is handling a\nsoft disconnect.  For a DWC3 based implementation, the callstack looks\nlike the following:\r\n\r\n    DWC3 Gadget                               FFS Application\ndwc3_gadget_soft_disconnect()              ...\n  --\u0026gt; dwc3_stop_active_transfers()\n    --\u0026gt; dwc3_gadget_giveback(-ESHUTDOWN)\n      --\u0026gt; ffs_epfile_async_io_complete()   ffs_aio_cancel()\n        --\u0026gt; usb_ep_free_request()            --\u0026gt; usb_ep_dequeue()\r\n\r\nThere is currently no locking implemented between the AIO completion\nhandler and AIO cancel, so the issue occurs if the completion routine is\nrunning in parallel to an AIO cancel call coming from the FFS application.\nAs the completion call frees the USB request (io_data-\u0026gt;req) the FFS\napplication is also referencing it for the usb_ep_dequeue() call.  This can\nlead to accessing a stale/hanging pointer.\r\n\r\ncommit b566d38857fc (\u0026quot;usb: gadget: f_fs: use io_data-\u0026gt;status consistently\u0026quot;)\nrelocated the usb_ep_free_request() into ffs_epfile_async_io_complete().\nHowever, in order to properly implement locking to mitigate this issue, the\nspinlock can\u0026apos;t be added to ffs_epfile_async_io_complete(), as\nusb_ep_dequeue() (if successfully dequeuing a USB request) will call the\nfunction driver\u0026apos;s completion handler in the same context.  Hence, leading\ninto a deadlock.\r\n\r\nFix this issue by moving the usb_ep_free_request() back to\nffs_user_copy_worker(), and ensuring that it explicitly sets io_data-\u0026gt;req\nto NULL after freeing it within the ffs-\u0026gt;eps_lock.  This resolves the race\ncondition above, as the ffs_aio_cancel() routine will not continue\nattempting to dequeue a request that has already been freed, or the\nffs_user_copy_work() not freeing the USB request until the AIO cancel is\ndone referencing it.\r\n\r\nThis fix depends on\n  commit b566d38857fc (\u0026quot;usb: gadget: f_fs: use io_data-\u0026gt;status\n  consistently\u0026quot;)(CVE-2024-36894)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nscsi: bfa: Ensure the copied buf is NUL terminated\r\n\r\nCurrently, we allocate a nbytes-sized kernel buffer and copy nbytes from\nuserspace to that buffer. Later, we use sscanf on this buffer but we don\u0026apos;t\nensure that the string is terminated inside the buffer, this can lead to\nOOB read when using sscanf. Fix this issue by using memdup_user_nul instead\nof memdup_user.(CVE-2024-38560)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nenic: Validate length of nl attributes in enic_set_vf_port\r\n\r\nenic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE\nis of length PORT_PROFILE_MAX and that the nl attributes\nIFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX.\nThese attributes are validated (in the function do_setlink in rtnetlink.c)\nusing the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE\nas NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and\nIFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation\nusing the policy is for the max size of the attributes and not on exact\nsize so the length of these attributes might be less than the sizes that\nenic_set_vf_port expects. This might cause an out of bands\nread access in the memcpys of the data of these\nattributes in enic_set_vf_port.(CVE-2024-38659)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbcache: fix variable length array abuse in btree_iter\r\n\r\nbtree_iter is used in two ways: either allocated on the stack with a\nfixed size MAX_BSETS, or from a mempool with a dynamic size based on the\nspecific cache set. Previously, the struct had a fixed-length array of\nsize MAX_BSETS which was indexed out-of-bounds for the dynamically-sized\niterators, which causes UBSAN to complain.\r\n\r\nThis patch uses the same approach as in bcachefs\u0026apos;s sort_iter and splits\nthe iterator into a btree_iter with a flexible array member and a\nbtree_iter_stack which embeds a btree_iter as well as a fixed-length\ndata array.(CVE-2024-39482)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrivers: core: synchronize really_probe() and dev_uevent()\r\n\r\nSynchronize the dev-\u0026gt;driver usage in really_probe() and dev_uevent().\nThese can run in different threads, what can result in the following\nrace condition for dev-\u0026gt;driver uninitialization:\r\n\r\nThread #1:\n==========\r\n\r\nreally_probe() {\n...\nprobe_failed:\n...\ndevice_unbind_cleanup(dev) {\n    ...\n    dev-\u0026gt;driver = NULL;   // \u0026lt;= Failed probe sets dev-\u0026gt;driver to NULL\n    ...\n    }\n...\n}\r\n\r\nThread #2:\n==========\r\n\r\ndev_uevent() {\n...\nif (dev-\u0026gt;driver)\n      // If dev-\u0026gt;driver is NULLed from really_probe() from here on,\n      // after above check, the system crashes\n      add_uevent_var(env, \u0026quot;DRIVER=%s\u0026quot;, dev-\u0026gt;driver-\u0026gt;name);\n...\n}\r\n\r\nreally_probe() holds the lock, already.

Otherwise we are risking garbage from the last word\nwe\u0026apos;d copied.\r\n\r\nFor most of the callers that is true - expand_fdtable() has\ncount equal to old-\u0026gt;max_fds, so there\u0026apos;s no open descriptors\npast count, let alone fully occupied words in -\u0026gt;open_fds[],\nwhich is what bits in -\u0026gt;full_fds_bits[] correspond to.\r\n\r\nThe other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),\nwhich is the smallest multiple of BITS_PER_LONG that covers all\nopened descriptors below max_fds.  In the common case (copying on\nfork()) max_fds is ~0U, so all opened descriptors will be below\nit and we are fine, by the same reasons why the call in expand_fdtable()\nis safe.\r\n\r\nUnfortunately, there is a case where max_fds is less than that\nand where we might, indeed, end up with junk in -\u0026gt;full_fds_bits[] -\nclose_range(from, to, CLOSE_RANGE_UNSHARE) with\n\t* descriptor table being currently shared\n\t* \u0026apos;to\u0026apos; being above the current capacity of descriptor table\n\t* \u0026apos;from\u0026apos; being just under some chunk of opened descriptors.\nIn that case we end up with observably wrong behaviour - e.g. spawn\na child with CLONE_FILES, get all descriptors in range 0..127 open,\nthen close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending\nup with descriptor #128, despite #64 being observably not open.\r\n\r\nThe minimally invasive fix would be to deal with that in dup_fd().\nIf this proves to add measurable overhead, we can go that way, but\nlet\u0026apos;s try to fix copy_fd_bitmaps() first.\r\n\r\n* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).\n* make copy_fd_bitmaps() take the bitmap size in words, rather than\nbits; it\u0026apos;s \u0026apos;count\u0026apos; argument is always a multiple of BITS_PER_LONG,\nso we are not losing any information, and that way we can use the\nsame helper for all three bitmaps - compiler will see that count\nis a multiple of BITS_PER_LONG for the large ones, so it\u0026apos;ll generate\nplain memcpy()+memset().\r\n\r\nReproducer added to tools/testing/selftests/core/close_range_test.c(CVE-2024-45025)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nscsi: aacraid: Fix double-free on probe failure\r\n\r\naac_probe_one() calls hardware-specific init functions through the\naac_driver_ident::init pointer, all of which eventually call down to\naac_init_adapter().\r\n\r\nIf aac_init_adapter() fails after allocating memory for aac_dev::queues,\nit frees the memory but does not clear that member.\r\n\r\nAfter the hardware-specific init function returns an error,\naac_probe_one() goes down an error path that frees the memory pointed to\nby aac_dev::queues, resulting.in a double-free.(CVE-2024-46673)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nusb: dwc3: st: fix probed platform device ref count on probe error path\r\n\r\nThe probe function never performs any paltform device allocation, thus\nerror path \u0026quot;undo_platform_dev_alloc\u0026quot; is entirely bogus.  It drops the\nreference count from the platform device being probed.
