Title
net: let net.core.dev_weight always be non-zero
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: let net.core.dev_weight always be non-zero
The following problem was encountered during stability test:
(NULL net_device): NAPI poll function process_backlog+0x0/0x530 \
returned 1, exceeding its budget of 0.
------------[ cut here ]------------
list_add double add: new=ffff88905f746f48, prev=ffff88905f746f48, \
next=ffff88905f746e40.

entry_SYSCALL_64_after_hwframe+0x76/0x7e
The reproduction command is as follows:
sysctl -w net.core.dev_weight=0
ping 127.0.0.1
This is because when the napi's weight is set to 0, process_backlog() may
return 0 and clear the NAPI_STATE_SCHED bit of napi->state, causing this
napi to be re-polled in net_rx_action() until __do_softirq() times out.
Since the NAPI_STATE_SCHED bit has been cleared, napi_schedule_rps() can
be retriggered in enqueue_to_backlog(), causing this issue.
Making the napi's weight always non-zero solves this problem.
Triggering this issue requires system-wide admin (setting is
not namespaced).

Title
nilfs2: protect access to buffers with no active references
Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: protect access to buffers with no active references
nilfs_lookup_dirty_data_buffers(), which iterates through the buffers
attached to dirty data folios/pages, accesses the attached buffers without
locking the folios/pages.
For data cache, nilfs_clear_folio_dirty() may be called asynchronously
when the file system degenerates to read only, so
nilfs_lookup_dirty_data_buffers() still has the potential to cause use
after free issues when buffers lose the protection of their dirty state
midway due to this asynchronous clearing and are unintentionally freed by
try_to_free_buffers().
Eliminate this race issue by adjusting the lock section in this function.

Title
ptp: Ensure info->enable callback is always set
Summary
In the Linux kernel, the following vulnerability has been resolved:
ptp: Ensure info->enable callback is always set
The ioctl and sysfs handlers unconditionally call the ->enable callback.
Not all drivers implement that callback, leading to NULL dereferences.
Example of affected drivers: ptp_s390.c, ptp_vclock.c and ptp_mock.c.
Instead use a dummy callback if no better was specified by the driver.
Severity
No CVSS data available.

Title
batman-adv: Drop unmanaged ELP metric worker
Summary
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: Drop unmanaged ELP metric worker
The ELP worker needs to calculate new metric values for all neighbors
"reachable" over an interface. Some of the used metric sources require
locks which might need to sleep. This sleep is incompatible with the RCU
list iterator used for the recorded neighbors. The initial approach to work
around of this problem was to queue another work item per neighbor and then
run this in a new context.
Even when this solved the RCU vs might_sleep() conflict, it has a major
problems: Nothing was stopping the work item in case it is not needed
anymore - for example because one of the related interfaces was removed or
the batman-adv module was unloaded - resulting in potential invalid memory
accesses.
Directly canceling the metric worker also has various problems:
* cancel_work_sync for a to-be-deactivated interface is called with
rtnl_lock held. But the code in the ELP metric worker also tries to use
rtnl_lock() - which will never return in this case. This also means that
cancel_work_sync would never return because it is waiting for the worker
to finish.
* iterating over the neighbor list for the to-be-deactivated interface is
currently done using the RCU specific methods. Which means that it is
possible to miss items when iterating over it without the associated
spinlock - a behaviour which is acceptable for a periodic metric check
but not for a cleanup routine (which must "stop" all still running
workers)
The better approch is to get rid of the per interface neighbor metric
worker and handle everything in the interface worker. The original problems
are solved by:
* creating a list of neighbors which require new metric information inside
the RCU protected context, gathering the metric according to the new list
outside the RCU protected context
* only use rcu_trylock inside metric gathering code to avoid a deadlock
when the cancel_delayed_work_sync is called in the interface removal code
(which is called with the rtnl_lock held)
Severity
7.8 (High)

Title
usb: gadget: f_midi: fix MIDI Streaming descriptor lengths
Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_midi: fix MIDI Streaming descriptor lengths
While the MIDI jacks are configured correctly, and the MIDIStreaming
endpoint descriptors are filled with the correct information,
bNumEmbMIDIJack and bLength are set incorrectly in these descriptors.
This does not matter when the numbers of in and out ports are equal, but
when they differ the host will receive broken descriptors with
uninitialized stack memory leaking into the descriptor for whichever
value is smaller.
The precise meaning of "in" and "out" in the port counts is not clearly
defined and can be confusing. But elsewhere the driver consistently
uses this to match the USB meaning of IN and OUT viewed from the host,
so that "in" ports send data to the host and "out" ports receive data
from it.
Severity
No CVSS data available.

Title
acct: perform last write from workqueue
Summary
In the Linux kernel, the following vulnerability has been resolved:
acct: perform last write from workqueue
In [1] it was reported that the acct(2) system call can be used to
trigger NULL deref in cases where it is set to write to a file that
triggers an internal lookup. This can e.g., happen when pointing acc(2)
to /sys/power/resume. At the point the where the write to this file
happens the calling task has already exited and called exit_fs(). A
lookup will thus trigger a NULL-deref when accessing current->fs.
Reorganize the code so that the the final write happens from the
workqueue but with the caller's credentials. This preserves the
(strange) permission model and has almost no regression risk.
This api should stop to exist though.

This can e.g., happen when pointing acc(2)\nto /sys/power/resume. At the point the where the write to this file\nhappens the calling task has already exited and called exit_fs(). A\nlookup will thus trigger a NULL-deref when accessing current-\u003efs.\n\nReorganize the code so that the the final write happens from the\nworkqueue but with the caller\u0027s credentials. This preserves the\n(strange) permission model and has almost no regression risk.\n\nThis api should stop to exist though."

Title
geneve: Fix use-after-free in geneve_find_dev().
Summary
In the Linux kernel, the following vulnerability has been resolved:
geneve: Fix use-after-free in geneve_find_dev().
syzkaller reported a use-after-free in geneve_find_dev() [0]
without repro.
geneve_configure() links struct geneve_dev.next to
net_generic(net, geneve_net_id)->geneve_list.
The net here could differ from dev_net(dev) if IFLA_NET_NS_PID,
IFLA_NET_NS_FD, or IFLA_TARGET_NETNSID is set.
When dev_net(dev) is dismantled, geneve_exit_batch_rtnl() finally
calls unregister_netdevice_queue() for each dev in the netns,
and later the dev is freed.
However, its geneve_dev.next is still linked to the backend UDP
socket netns.
Then, use-after-free will occur when another geneve dev is created
in the netns.
Let's call geneve_dellink() instead in geneve_destroy_tunnels().

"value": "AV:L - The vulnerability is reached only through RTM_NEWLINK rtnetlink messages sent on an AF_NETLINK socket, requiring local system access. The geneve_list is used solely by the control plane (geneve_configure/geneve_dellink), never by the packet receive path, so no remote packet can trigger it.\nAC:L - The attacker deterministically creates both network namespaces, creates the geneve device cross-netns, destroys the device-owning netns, then creates a second geneve device to dereference the stale list entry \u2014 no race must be won and the dangling pointer persists indefinitely, allowing unhurried heap grooming of the freed 4096-byte slab object.\nPR:L - CAP_NET_ADMIN is required in the owning user namespaces of both netns, but an unprivileged user obtains exactly that with `unshare -Urn` plus a nested `unshare -n`, since both namespaces are owned by their own user_ns and the checks are ns_capable-based. The geneve module is autoloaded on demand from the same unprivileged rtnl_newlink path.\nUI:N - The full sequence is performed by the attacker\u0027s own processes via netlink and namespace file descriptors, with no action by any other user.\nS:U - The use-after-free corrupts kernel heap state and is exploited for kernel privilege escalation within the same security authority; no hypervisor, IOMMU, or other authority boundary is crossed.\nC:H - The stale list entry points into a freed kmalloc-cg-4k object the attacker can reallocate and fill, so the list traversal in geneve_find_dev() follows an attacker-controlled `next` pointer and reads arbitrary kernel addresses, with the -EBUSY/-EPERM/success result acting as a disclosure oracle.\nI:H - Later list_del()/list_add() operations on the corrupted geneve_list write through attacker-controlled prev/next pointers, yielding a classic unlink write-what-where primitive suitable for control-flow hijacking and privilege escalation.\nA:H - The bug is a confirmed slab use-after-free (KASAN slab-use-after-free reported by syzkaller) that reliably corrupts a kernel linked list, causing oops or panic even without successful exploitation."

Title
USB: gadget: f_midi: f_midi_complete to call queue_work
Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: f_midi: f_midi_complete to call queue_work
When using USB MIDI, a lock is attempted to be acquired twice through a
re-entrant call to f_midi_transmit, causing a deadlock.
Fix it by using queue_work() to schedule the inner f_midi_transmit() via
a high priority work queue from the completion handler.
