| In the Linux kernel, the following vulnerability has been resolved:
ASoC: qcom: audioreach: fix potential null pointer dereference
It is possible that the topology parsing function
audioreach_widget_load_module_common() could return NULL or an error
pointer. Add missing NULL check so that we do not dereference it. |
| In the Linux kernel, the following vulnerability has been resolved:
fpga: prevent integer overflow in dfl_feature_ioctl_set_irq()
The "hdr.count * sizeof(s32)" multiplication can overflow on 32 bit
systems leading to memory corruption. Use array_size() to fix that. |
| In the Linux kernel, the following vulnerability has been resolved:
media: i2c: tc358743: Fix use-after-free bugs caused by orphan timer in probe
The state->timer is a cyclic timer that schedules work_i2c_poll and
delayed_work_enable_hotplug, while rearming itself. Using timer_delete()
fails to guarantee the timer isn't still running when destroyed, similarly
cancel_delayed_work() cannot ensure delayed_work_enable_hotplug has
terminated if already executing. During probe failure after timer
initialization, these may continue running as orphans and reference the
already-freed tc358743_state object through tc358743_irq_poll_timer.
The following is the trace captured by KASAN.

Replace timer_delete() with timer_delete_sync() and cancel_delayed_work()
with cancel_delayed_work_sync() to ensure proper termination of timer and
work items before resource cleanup.
This bug was initially identified through static analysis. For reproduction
and testing, I created a functional emulation of the tc358743 device via a
kernel module and introduced faults through the debugfs interface. |

| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix the error "trying to register non-static key in rxe_cleanup_task"
In the function rxe_create_qp(), rxe_qp_from_init() is called to
initialize qp, internally things like rxe_init_task are not setup until
rxe_qp_init_req().
If an error occurred before this point then the unwind will call
rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()
which will oops when trying to access the uninitialized spinlock.
If rxe_init_task is not executed, rxe_cleanup_task will not be called. |

net: ipv4: fix one memleak in __inet_del_ifa()
I got the below warning when do fuzzing test:
unregister_netdevice: waiting for bond0 to become free. Usage count = 2
It can be repoduced via:
ip link add bond0 type bond
sysctl -w net.ipv4.conf.bond0.promote_secondaries=1
ip addr add 4.117.174.103/0 scope 0x40 dev bond0
ip addr add 192.168.100.111/255.255.255.254 scope 0 dev bond0
ip addr add 0.0.0.4/0 scope 0x40 secondary dev bond0
ip addr del 4.117.174.103/0 scope 0x40 dev bond0
ip link delete bond0 type bond
In this reproduction test case, an incorrect 'last_prim' is found in
__inet_del_ifa(), as a result, the secondary address(0.0.0.4/0 scope 0x40)
is lost. The memory of the secondary address is leaked and the reference of
in_device and net_device is leaked.
Fix this problem:
Look for 'last_prim' starting at location of the deleted IP and inserting
the promoted IP into the location of 'last_prim'. |

ASoC: Intel: avs: Disable periods-elapsed work when closing PCM
avs_dai_fe_shutdown() handles the shutdown procedure for HOST HDAudio
stream while period-elapsed work services its IRQs. As the former
frees the DAI's private context, these two operations shall be

Don't add BO to the vdev->bo_list in ivpu_gem_create_object().
When failure happens inside drm_gem_shmem_create(), the BO is not
fully created and ivpu_gem_bo_free() callback will not be called

| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Prevent potential UAF in group creation
This commit prevents the possibility of a use after free issue in the
GROUP_CREATE ioctl function, which arose as pointer to the group is
accessed in that ioctl function after storing it in the Xarray.
A malicious userspace can second guess the handle of a group and try
to call GROUP_DESTROY ioctl from another thread around the same time
as GROUP_CREATE ioctl.
To prevent the use after free exploit, this commit uses a mark on an
entry of group pool Xarray which is added just before returning from
the GROUP_CREATE ioctl function. The mark is checked for all ioctls
that specify the group handle and so userspace won't be abe to delete
a group that isn't marked yet.

| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Fix UAF race between device unplug and FW event processing
The function panthor_fw_unplug() will free the FW memory sections.
The problem is that there could still be pending FW events which are yet
not handled at this point. process_fw_events_work() can in this case try
to access said freed memory.
Simply call disable_work_sync() to both drain and prevent future
invocation of process_fw_events_work(). |

Fix the issue detecting the proper wed reference to use running wed
callabacks. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: Fix resource leak in ksmbd_session_rpc_open()
When ksmbd_rpc_open() fails then it must call ksmbd_rpc_id_free() to
undo the result of ksmbd_ipc_id_alloc(). |
| In the Linux kernel, the following vulnerability has been resolved:
pwm: berlin: Fix wrong register in suspend/resume
The 'enable' register should be BERLIN_PWM_EN rather than
BERLIN_PWM_ENABLE, otherwise, the driver accesses wrong address, there
will be cpu exception then kernel panic during suspend/resume. |
| In the Linux kernel, the following vulnerability has been resolved:
ipmi: Rework user message limit handling
The limit on the number of user messages had a number of issues,
improper counting in some cases and a use after free.
Restructure how this is all done to handle more in the receive message
allocation routine, so all refcouting and user message limit counts
are done in that routine. It's a lot cleaner and safer. |
| Improper input validation in the Linux kernel-mode driver for some Intel(R) 700 Series Ethernet before version 2.28.5 may allow an authenticated user to potentially enable escalation of privilege via local access. |
| Nokia SR Linux is vulnerable to an authentication vulnerability allowing unauthorized access to the JSON-RPC service. When exploited, an invalid validation allows JSON RPC access without providing valid authentication credentials. |
| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: fix memory leak in bnxt_nvm_test()
Free the kzalloc'ed buffer before returning in the success path. |
