CVE-2024-53063 (GCVE-0-2024-53063)

Title
media: dvbdev: prevent the risk of out of memory access
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: dvbdev: prevent the risk of out of memory access
The dvbdev contains a static variable used to store dvb minors.
The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set
or not. When not set, dvb_register_device() won't check for
boundaries, as it will rely that a previous call to
dvb_register_adapter() would already be enforcing it.
On a similar way, dvb_device_open() uses the assumption
that the register functions already did the needed checks.
This can be fragile if some device ends using different
calls. This also generate warnings on static check analysers
like Coverity.
So, add explicit guards to prevent potential risk of OOM issues.

Exploitation does not depend on any probabilistic condition.\nPR:L - `dvb_device_open()` performs no capability or permission check of its own; reaching it needs only the ability to open a DVB character device, which on set-top boxes, Android TV, media appliances, and desktop tuner systems is granted to ordinary users via the `video` group. No root or CAP_SYS_ADMIN is required by the code path itself.\nUI:N - The attacker triggers the path entirely on their own by issuing `open()` on the device node. No victim action, mount, or interaction with another user is required.\nS:U - The out-of-bounds access, the wild pointer dereference, and any resulting code execution all occur within the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `dvb_minors[iminor(inode)]` is an unbounded read past the end of a static array, and the value read is used as a `struct dvb_device *` whose fields are dereferenced \u2014 the read is not limited to a few known bytes. Per kernel guidance an out-of-bounds read of this kind, usable to influence and observe kernel state, is High.\nI:H - The out-of-bounds-read pointer\u0027s `-\u003efops` is fetched with `fops_get()`, installed into the file via `replace_fops()`, and then `file-\u003ef_op-\u003eopen(inode, file)` is called \u2014 an indirect branch through a function-pointer table taken from memory outside the array bounds, which is a control-flow hijack primitive rather than a mere read fault.\nA:H - Dereferencing a garbage pointer read past the array, and calling through its `fops` table, faults on an unmapped or non-executable kernel address, producing an oops or panic. The condition is repeatable on every `open()` attempt."

The KMSAN warning is triggered in decode_getfattr_attrs(), when calling
decode_attr_mdsthreshold(). It appears that fattr->mdsthreshold is not
initialized.
Fix the issue by initializing fattr->mdsthreshold to NULL in
nfs_fattr_init().

Title
netlink: terminate outstanding dump on socket close
Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: terminate outstanding dump on socket close
Netlink supports iterative dumping of data. It provides the families
the following ops:
- start - (optional) kicks off the dumping process
- dump - actual dump helper, keeps getting called until it returns 0
- done - (optional) pairs with .start, can be used for cleanup
The whole process is asynchronous and the repeated calls to .dump
don't actually happen in a tight loop, but rather are triggered
in response to recvmsg() on the socket.
This gives the user full control over the dump, but also means that
the user can close the socket without getting to the end of the dump.
To make sure .start is always paired with .done we check if there
is an ongoing dump before freeing the socket, and if so call .done.
The complication is that sockets can get freed from BH and .done
is allowed to sleep. So we use a workqueue to defer the call, when
needed.
Unfortunately this does not work correctly. What we defer is not
the cleanup but rather releasing a reference on the socket.
We have no guarantee that we own the last reference, if someone
else holds the socket they may release it in BH and we're back
to square one.
The whole dance, however, appears to be unnecessary. Only the user
can interact with dumps, so we can clean up when socket is closed.
And close always happens in process context. Some async code may
still access the socket after close, queue notification skbs to it etc.
but no dumps can start, end or otherwise make progress.
Delete the workqueue and flush the dump state directly from the release
handler. Note that further cleanup is possible in -next, for instance
we now always call .done before releasing the main module reference,
so dump doesn't have to take a reference of its own.

It provides the families\nthe following ops:\n - start - (optional) kicks off the dumping process\n - dump - actual dump helper, keeps getting called until it returns 0\n - done - (optional) pairs with .start, can be used for cleanup\nThe whole process is asynchronous and the repeated calls to .dump\ndon\u0027t actually happen in a tight loop, but rather are triggered\nin response to recvmsg() on the socket.\n\nThis gives the user full control over the dump, but also means that\nthe user can close the socket without getting to the end of the dump.\nTo make sure .start is always paired with .done we check if there\nis an ongoing dump before freeing the socket, and if so call .done.\n\nThe complication is that sockets can get freed from BH and .done\nis allowed to sleep. So we use a workqueue to defer the call, when\nneeded.\n\nUnfortunately this does not work correctly. What we defer is not\nthe cleanup but rather releasing a reference on the socket.\nWe have no guarantee that we own the last reference, if someone\nelse holds the socket they may release it in BH and we\u0027re back\nto square one.\n\nThe whole dance, however, appears to be unnecessary. Only the user\ncan interact with dumps, so we can clean up when socket is closed.\nAnd close always happens in process context. Some async code may\nstill access the socket after close, queue notification skbs to it etc.\nbut no dumps can start, end or otherwise make progress.\n\nDelete the workqueue and flush the dump state directly from the release\nhandler. Note that further cleanup is possible in -next, for instance\nwe now always call .done before releasing the main module reference,\nso dump doesn\u0027t have to take a reference of its own."

Title
NFSv4.0: Fix a use-after-free problem in the asynchronous open()
Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4.0: Fix a use-after-free problem in the asynchronous open()
Yang Erkun reports that when two threads are opening files at the same
time, and are forced to abort before a reply is seen, then the call to
nfs_release_seqid() in nfs4_opendata_free() can result in a
use-after-free of the pointer to the defunct rpc task of the other
thread.
The fix is to ensure that if the RPC call is aborted before the call to
nfs_wait_on_sequence() is complete, then we must call nfs_release_seqid()
in nfs4_open_release() before the rpc_task is freed.

A malicious or unresponsive server only influences timing, it cannot initiate the opens itself.\nAC:L - The attacker controls both sides of the race: state owners are keyed by credential, so several threads of the same unprivileged user opening files on the same NFSv4.0 mount are forcibly serialized on one seqid list, and the attacker chooses the thread count, the open pattern, and when to abort them with fatal signals, retrying in a loop until the window is hit. An NFSv4.0 mount is a common, non-exotic deployment (and a server can negotiate the client down to 4.0), so no condition outside attacker control is required.\nPR:L - Any unprivileged local user with access to an NFSv4.0 mount can trigger this \u2014 the path is reached through the ordinary `open()` syscall with no capability, and the aborts are just fatal signals delivered to the attacker\u0027s own threads.

In 'hci_conn_del_sysfs()', 'device_unregister()' may be called when
an underlying (kobject) reference counter is greater than 1. This
means that reparenting (happened when the device is actually freed)
is delayed and, during that delay, parent controller device (hciX)
may be deleted. Since the latter may create a dangling pointer to
freed parent, avoid that scenario by reparenting to NULL explicitly.

Per kernel scoring guidance and repo precedent for BNEP/HIDP lifetime UAFs, Bluetooth reachability is Adjacent.\nAC:L - The attacker drives both halves of the lifetime race by repeatedly connecting and abruptly disconnecting, and connection teardown reliably reaches `hci_conn_del_sysfs()` with a non-rfcomm child still attached, leaving the dangling grandparent pointer every time. No condition depends on memory layout or state the attacker cannot influence.\nPR:N - The attacker is an unauthenticated adjacent Bluetooth device with no local account; the `capable(CAP_NET_ADMIN)` gate on `BNEPCONNADD` is satisfied by bluetoothd acting on the peer\u0027s behalf during normal PAN/HID service handling. This matches how the kernel CNA scored the comparable bnep/HIDP UAFs.\nUI:N - No victim action is needed \u2014 session teardown is triggered by the attacker\u0027s own disconnect, and controller unregistration occurs routinely via suspend/resume, USB dongle reset, firmware error recovery, or driver reload.\nS:U - The corrupted `hci_dev` object and the faulting code both live in the kernel\u0027s own security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - `device_for_each_child()` dereferences `dev-\u003ep` and walks `klist_children` inside the freed `hci_dev` slab, so an attacker who reclaims and sprays that large kmalloc allocation can steer the traversal to read arbitrary kernel memory.\nI:H - The traversal is not read-only \u2014 `klist_iter_init()` takes `spin_lock(\u0026k-\u003ek_lock)` and `kref_get()` increments refcounts through pointers taken from the freed object, yielding attacker-influenced writes and a classic UAF heap-corruption primitive suitable for control-flow hijack.\nA:H - Confirmed by the syzbot KASAN slab-use-after-free report; dereferencing the freed `hci_dev` and walking a stale klist produces a kernel oops or lockup, remotely inducible by an adjacent peer."

"value": "AV:L - The malicious data is on-disk JFS directory-btree metadata consumed locally via `mount(2)` followed by `getdents(2)` on the crafted directory; no network- or peer-supplied data reaches `dtReadFirst()`. The image is delivered as removable media, a loop-mountable file, or a container/appliance disk blob.\nAC:L - The attacker sets `stbl[0]` to any negative value directly in the on-disk image, so the out-of-bounds index and its exact -32..-4096 byte offset are fully attacker-chosen and fire deterministically on the first `readdir()` of the crafted directory. There is no race, timing window, or memory-layout condition outside the attacker\u0027s influence.\nPR:N - The attacker needs no account or privilege on the target system \u2014 they only author the crafted JFS image, and the privileged mount is performed by the victim or by automounting tooling. This matches the established scoring for crafted-filesystem-image CVEs in this subsystem.\nUI:R - JFS is `FS_REQUIRES_DEV` without `FS_USERNS_MOUNT`, so the attacker cannot mount the image themselves; a victim (root, udisks/automounter, or image-processing automation) must mount it and then list the directory, though a single `ls` is enough once mounted.\nS:U - The out-of-bounds read and any resulting fault stay inside the kernel of the same host; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The attacker selects any 8-byte window across a 4 KB region preceding the dtree page \u2014 for the root case that is inside `struct jfs_inode_info` and neighbouring slab objects, exposing kernel pointers such as `ipimap` and `anon_inode_list` \u2014 so the read is far from \"strictly bounded to a few bytes.\" The leaked bytes become `bn`/`psize` and select which attacker-authored disk block is fetched and listed, giving an observable oracle that exfiltrates the disclosed kernel memory through `readdir()` output.\nI:N - `xd` is only dereferenced for reading in `dtReadFirst()`; the out-of-bounds access performs no kernel memory write and yields no corruption or control-flow primitive. The only writes it can steer (`add_missing_indices()`) land on blocks of the attacker\u0027s own crafted block device, not on victim-owned kernel or system state.\nA:H - This is the syzbot-reported UBSAN array-index-out-of-bounds; on `CONFIG_UBSAN_BOUNDS` + `CONFIG_UBSAN_TRAP` builds (Android GKI and hardened kernels) the check traps into a kernel panic, and on KASAN/`panic_on_warn` configurations the slab-out-of-bounds report is fatal. The garbage `bn`/`psize` additionally drives `jfs_error()` paths that panic under `errors=panic`, and the trigger is repeatable on every `readdir()` of the crafted directory."

Title
scsi: sg: Fix slab-use-after-free read in sg_release()
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: sg: Fix slab-use-after-free read in sg_release()
Fix a use-after-free bug in sg_release(), detected by syzbot with KASAN:
BUG: KASAN: slab-use-after-free in lock_release+0x151/0xa30
kernel/locking/lockdep.c:5838
__mutex_unlock_slowpath+0xe2/0x750 kernel/locking/mutex.c:912
sg_release+0x1f4/0x2e0 drivers/scsi/sg.c:407
In sg_release(), the function kref_put(&sfp->f_ref, sg_remove_sfp) is
called before releasing the open_rel_lock mutex. The kref_put() call may
decrement the reference count of sfp to zero, triggering its cleanup
through sg_remove_sfp(). This cleanup includes scheduling deferred work
via sg_remove_sfp_usercontext(), which ultimately frees sfp.
After kref_put(), sg_release() continues to unlock open_rel_lock and may
reference sfp or sdp. If sfp has already been freed, this results in a
slab-use-after-free error.
Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking the
open_rel_lock mutex. This ensures:
- No references to sfp or sdp occur after the reference count is
decremented.
- Cleanup functions such as sg_remove_sfp() and
sg_remove_sfp_usercontext() can safely execute without impacting the
mutex handling in sg_release().
The fix has been tested and validated by syzbot. This patch closes the
bug reported at the following syzkaller link and ensures proper
sequencing of resource cleanup and mutex operations, eliminating the
risk of use-after-free errors in sg_release().

That is ordinary low-privilege access, not real root.\nUI:N - The attacker performs `open()` and `close()` on the device node entirely on their own; no victim action is needed to trigger the use-after-free.\nS:U - The freed `struct sg_device` and the resulting corruption are both within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - The freed `sg_device` slab object can be reclaimed by attacker-sprayed data and is subsequently read by `mutex_unlock()`/`lock_release()` and the waitqueue walk, giving control over dereferenced pointers that can be leveraged into arbitrary kernel memory disclosure.\nI:H - After the free, `sg_release()` still performs `sdp-\u003eopen_cnt--`, `sdp-\u003eexclude = false`, waitqueue list manipulation and `mutex_unlock()` on the freed object, yielding write primitives into reclaimed heap memory that are exploitable for control-flow hijacking and privilege escalation.\nA:H - The use-after-free reliably corrupts kernel slab memory and touches a freed mutex and waitqueue, producing KASAN splats, lockdep faults, and kernel panics \u2014 a full system crash."

Title
tipc: Fix use-after-free of kernel socket in cleanup_bearer().
Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: Fix use-after-free of kernel socket in cleanup_bearer().
syzkaller reported a use-after-free of UDP kernel socket
in cleanup_bearer() without repro. [0][1]
When bearer_disable() calls tipc_udp_disable(), cleanup
of the UDP kernel socket is deferred by work calling
cleanup_bearer().
tipc_exit_net() waits for such works to finish by checking
tipc_net(net)->wq_count. However, the work decrements the
count too early before releasing the kernel socket,
unblocking cleanup_net() and resulting in use-after-free.
Let's move the decrement after releasing the socket in
cleanup_bearer().

"value": "AV:L - The vulnerability is reached through generic netlink (TIPC_NL_BEARER_ENABLE/DISABLE) plus network-namespace teardown, both of which require local access to the machine. A remote TIPC/UDP peer cannot cause bearer teardown or netns destruction, so this is not remotely triggerable.\nAC:L - The attacker controls both sides of the race \u2014 creating/destroying the netns and enabling/disabling up to three UDP bearers, repeatedly and in parallel \u2014 and the post-decrement window contains a sleepable free_percpu() in dst_cache_destroy() that can be stalled with attacker-generated load, so the race can be won reliably by looping.\nPR:L - At the time of this bug the TIPCv2 netlink mutators carried no GENL_ADMIN_PERM flag, so a fully unprivileged local user could enable/disable a UDP bearer (later confirmed and fixed by commit 86b0c540e2ea), and the netns teardown that arms the race is available to any user via unshare -Urn; even with the later gate, CAP_NET_ADMIN is obtainable in a user namespace.\nUI:N - The attacker performs every step itself \u2014 load the module, enable the bearer, tear down the namespace \u2014 with no action required from any other user.\nS:U - The use-after-free corrupts kernel memory and is exploited within the same kernel security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - The freed struct net is read after free in udp_lib_unhash() (udp table pointer, net_hash_mix), and reallocation of the net_cachep object gives the attacker control over the dereferenced contents, enabling kernel memory disclosure.\nI:H - After the struct net is freed, sock_prot_inuse_add() performs this_cpu_add() through a percpu pointer read from freed memory and udp_lib_unhash() takes a spinlock and does list removal through an attacker-influenceable table pointer, yielding a controlled write primitive suitable for privilege escalation.\nA:H - The use-after-free reliably corrupts the UDP hash slots and dereferences freed netns memory, producing kernel oops/panic (as captured by the KMSAN report), and can be triggered repeatedly by an unprivileged user."

Since an invalid (without '\0' byte at all) byte sequence may be passed
from userspace, add an extra check to ensure that such a sequence is
rejected as possible ID and so never passed to 'kstrdup()' and further.

Title
can: hi311x: hi3110_can_ist(): fix potential use-after-free
Summary
In the Linux kernel, the following vulnerability has been resolved:
can: hi311x: hi3110_can_ist(): fix potential use-after-free
The commit a22bd630cfff ("can: hi311x: do not report txerr and rxerr
during bus-off") removed the reporting of rxerr and txerr even in case
of correct operation (i. e. not bus-off).
The error count information added to the CAN frame after netif_rx() is
a potential use after free, since there is no guarantee that the skb
is in the same state. It might be freed or reused.
Fix the issue by postponing the netif_rx() call in case of txerr and
rxerr reporting.

CAN is a bounded shared bus, matching the CVSS \"logically adjacent topology\" definition rather than routable Network.\nAC:L - The free is deterministic, not a race \u2014 in threaded-IRQ context netif_rx() drains NET_RX_SOFTIRQ inline via local_bh_enable(), so process_backlog() consumes and frees the skb before netif_rx() returns, and the driver then unconditionally writes through the stale cf pointer. Driving TEC/REC across the error-warning/passive thresholds is entirely under the bus attacker\u0027s control and repeatable.\nPR:N - CAN provides no authentication, addressing, or access control; a peer node needs no credentials or account on the target system to inject the error conditions that trigger the path. The code path is also not gated by any ctrlmode flag or capability check.\nUI:N - No victim action is required \u2014 the CAN interface being up is normal operational state for a deployed device, and the interrupt handler runs automatically on controller error signalling.\nS:U - The use-after-free corrupts kernel slab memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed skb buffer is immediately recycled, so subsequent kernel data can occupy it while a socket may still hold references to the corrupted frame, and UAF-corrupted skb metadata can be leveraged to disclose adjacent kernel heap contents.\nI:H - This is a use-after-free write: a bit-set at offset 0 plus two bytes at offsets 14/15 of the freed allocation, with values (txerr/rxerr) the bus attacker influences, repeatable on every error-state transition \u2014 a heap-grooming-friendly write primitive into reallocated kernel objects.\nA:H - Writing into freed and reallocated slab memory corrupts unrelated kernel structures, causing oops, slab corruption, or panic, and the trigger can be repeated indefinitely from the bus."
