Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2022-2873
Zheyu Ma discovered that an out-of-bounds memory access flaw in
the Intel iSMT SMBus 2.0 host controller driver may result in
denial of service (system crash).

CVE-2022-3545
It was discovered that the Netronome Flow Processor (NFP) driver
contained a use-after-free flaw in area_cache_get(), which may
result in denial of service or the execution of arbitrary code.

CVE-2022-3623
A race condition when looking up a CONT-PTE/PMD size hugetlb page
may result in denial of service or an information leak.

CVE-2022-4696
A use-after-free vulnerability was discovered in the io_uring
subsystem.

CVE-2022-36280
An out-of-bounds memory write vulnerability was discovered in the
vmwgfx driver, which may allow a local unprivileged user to cause
a denial of service (system crash).

CVE-2022-41218
Hyunwoo Kim reported a use-after-free flaw in the Media DVB core
subsystem caused by refcount races, which may allow a local user
to cause a denial of service or escalate privileges.

CVE-2022-45934
An integer overflow in l2cap_config_req() in the Bluetooth
subsystem was discovered, which may allow a physically proximate
attacker to cause a denial of service (system crash).

CVE-2022-47929
Frederick Lawler reported a NULL pointer dereference in the
traffic control subsystem allowing an unprivileged user to cause a
denial of service by setting up a specially crafted traffic
control configuration.

CVE-2023-0179
Davide Ornaghi discovered incorrect arithmetics when fetching VLAN
header bits in the netfilter subsystem, allowing a local user to
leak stack and heap addresses or potentially local privilege
escalation to root.

CVE-2023-0240
A flaw was discovered in the io_uring subsystem that could lead
to a use-after-free. A local user could exploit this to cause
a denial of service (crash or memory corruption) or possibly for
privilege escalation.

CVE-2023-0266
A use-after-free flaw in the sound subsystem due to missing
locking may result in denial of service or privilege escalation.

CVE-2023-0394
Kyle Zeng discovered a NULL pointer dereference flaw in
rawv6_push_pending_frames() in the network subsystem allowing a
local user to cause a denial of service (system crash).

CVE-2023-23454
Kyle Zeng reported that the Class Based Queueing (CBQ) network
scheduler was prone to denial of service due to interpreting
classification results before checking the classification return
code.

CVE-2023-23455
Kyle Zeng reported that the ATM Virtual Circuits (ATM) network
scheduler was prone to a denial of service due to interpreting
classification results before checking the classification return
code.

CVE-2023-23586
A flaw was discovered in the io_uring subsystem that could lead to
an information leak. A local user could exploit this to obtain
sensitive information from the kernel or other users.

This update also fixes Debian bugs #825141, #1008501, #1027430, and
#1027483, and includes many more bug fixes from stable updates
5.10.159-5.10.162 inclusive.
