| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: ocb: don't leave if not joined
If there's no OCB state, don't ask the driver/mac80211 to
leave, since that's just confusing. Since set/clear the
chandef state, that's a simple check. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI/DOE: Fix memory leak with CONFIG_DEBUG_OBJECTS=y
After a pci_doe_task completes, its work_struct needs to be destroyed
to avoid a memory leak with CONFIG_DEBUG_OBJECTS=y. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Handle lock during peer_id find
ath12k_peer_find_by_id() requires that the caller hold the
ab->base_lock. Currently the WBM error path does not hold
the lock and calling that function, leads to the
following lockdep_assert()in QCN9274:

| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Prevent access to vCPU events before init
Another day, another syzkaller bug. KVM erroneously allows userspace to
pend vCPU events for a vCPU that hasn't been initialized yet, leading to
KVM interpreting a bunch of uninitialized garbage for routing /
injecting the exception.
In one case the injection code and the hyp disagree on whether the vCPU
has a 32bit EL1 and put the vCPU into an illegal mode for AArch64,
tripping the BUG() in exception_target_el() during the next injection:

Reject the ioctls outright as no sane VMM would call these before
KVM_ARM_VCPU_INIT anyway. Even if it did the exception would've been
thrown away by the eventual reset of the vCPU's state. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: s390: pv: fix index value of replaced ASCE
The index field of the struct page corresponding to a guest ASCE should
be 0. When replacing the ASCE in s390_replace_asce(), the index of the
new ASCE should also be set to 0.
Having the wrong index might lead to the wrong addresses being passed
around when notifying pte invalidations, and eventually to validity
intercepts (VM crash) if the prefix gets unmapped and the notifier gets
called with the wrong address. |
| In the Linux kernel, the following vulnerability has been resolved:

layer. This prevents the warning. |
| 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:
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:
nvmem: core: Fix memleak in nvmem_register()
dev_set_name will alloc memory for nvmem->dev.kobj.name in
nvmem_register, when nvmem_validate_keepouts failed, nvmem's
memory will be freed and return, but nobody will free memory
for nvmem->dev.kobj.name, there will be memleak, so moving
nvmem_validate_keepouts() after device_register() and let
the device core deal with cleaning name in error cases. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Avoid UBSAN error on true_sectors_per_clst()
syzbot reported UBSAN error as below:
[ 76.901829][ T6677] ================================================================================

[ 76.905363][ T6677] shift exponent -247 is negative
This patch avoid this error. |
| 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. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: use hdev->workqueue when queuing hdev->{cmd,ncmd}_timer works
syzbot is reporting attempt to schedule hdev->cmd_work work from system_wq
WQ into hdev->workqueue WQ which is under draining operation [1], for
commit c8efcc2589464ac7 ("workqueue: allow chained queueing during
destruction") does not allow such operation.
The check introduced by commit 877afadad2dce8aa ("Bluetooth: When HCI work
queue is drained, only queue chained work") was incomplete.
Use hdev->workqueue WQ when queuing hdev->{cmd,ncmd}_timer works because
hci_{cmd,ncmd}_timeout() calls queue_work(hdev->workqueue). Also, protect
the queuing operation with RCU read lock in order to avoid calling
queue_delayed_work() after cancel_delayed_work() completed. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: wed: use proper wed reference in mt76 wed driver callabacks
MT7996 driver can use both wed and wed_hif2 devices to offload traffic
from/to the wireless NIC. In the current codebase we assume to always
use the primary wed device in wed callbacks resulting in the following
crash if the hw runs wed_hif2 (e.g. 6GHz link).

Fix the issue detecting the proper wed reference to use running wed
callabacks. |
| In the Linux kernel, the following vulnerability has been resolved:
cifs: fix session state check in reconnect to avoid use-after-free issue
Don't collect exiting session in smb2_reconnect_server(), because it
will be released soon.
Note that the exiting session will stay in server->smb_ses_list until
it complete the cifs_free_ipc() and logoff() and then delete itself
from the list. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Fix page fault in ivpu_bo_unbind_all_bos_from_context()
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
causing a deleted BO to be left on the list. |
| In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: hold queue_lock when removing blkg->q_node
When blkg is removed from q->blkg_list from blkg_free_workfn(), queue_lock
has to be held, otherwise, all kinds of bugs(list corruption, hard lockup,
..) can be triggered from blkg_destroy_all(). |
| 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(). |
| In the Linux kernel, the following vulnerability has been resolved:
igc: Fix Kernel Panic during ndo_tx_timeout callback
The Xeon validation group has been carrying out some loaded tests
with various HW configurations, and they have seen some transmit
queue time out happening during the test. This will cause the
reset adapter function to be called by igc_tx_timeout().
Similar race conditions may arise when the interface is being brought
down and up in igc_reinit_locked(), an interrupt being generated, and
igc_clean_tx_irq() being called to complete the TX.
When the igc_tx_timeout() function is invoked, this patch will turn
off all TX ring HW queues during igc_down() process. TX ring HW queues
will be activated again during the igc_configure_tx_ring() process
when performing the igc_up() procedure later.
This patch also moved existing igc_disable_tx_ring_hw() to avoid using
forward declaration.

| In the Linux kernel, the following vulnerability has been resolved:
media: dvb-usb: m920x: Fix a potential memory leak in m920x_i2c_xfer()
'read' is freed when it is known to be NULL, but not when a read error
occurs.
Revert the logic to avoid a small leak, should a m920x_read() call fail. |
| In the Linux kernel, the following vulnerability has been resolved:
cifs: fix potential race when tree connecting ipc
Protect access of TCP_Server_Info::hostname when building the ipc tree
name as it might get freed in cifsd thread and thus causing an
use-after-free bug in __tree_connect_dfs_target(). Also, while at it,
update status of IPC tcon on success and then avoid any extra tree
connects. |
