A flaw in Intel HD Graphics Driver when flushing translation lookaside
buffers could allow access to physical memory which might be already
assigned to a different process. A local user could use this flaw for
denial-of-service or information disclosure.

* CVE-2022-3435: Information disclosure in IPv4.

A flaw in ioctls of IPv4 could result in out-of-bounds read access.

A flaw in ioctls of NVM Express block device could result in PCIe link
disconnect. A local user could use this flaw for a denial-of-service.

* CVE-2022-4378: Out-of-bounds memory access in sysctl.

A flaw parsing character strings in the sysctl subsystem when changing
kernel parameters can lead to a stack overflow. A local user could use
this flaw for a denial-of-service or arbitrary code execution.

* Improved update to CVE-2022-3643: Denial-of-host-service via malicious Xen netfront packet.

The Xen netback handler does not properly handle packets with protocol
headers that span multiple slots. A malicious guest might exploit this
to crash certain varieties of network interface on the host.

* CVE-2022-3623: Information disclosure in HugeTLB file system support.

A flaw in HugeTLB file system support when looking up a hugetlb page in
some situations could lead to a race condition. A local user could use
this flaw to cause a denial-of-service or information disclosure.

* CVE-2022-3424: Denial-of-service in SGI GRU driver.

A logic error when using SGI GRU driver could lead to a use-after-free.
A local attacker could use this flaw to cause a denial-of-service.

* CVE-2022-2873: Out-of-bounds memory access in iSMT.

A missing sanity check for a user controlled value in the Intel's iSMT
SMBus host controller driver when processing an SMBus command may lead
to a memory corruption by writing past the end of a buffer. A local
user could use this flaw for denial-of-service or code execution.

* CVE-2022-41218: Use-after-free in dvb-core device release path.

Improper locking during device release operations can lead to a
use-after-free error in the dvb-core driver.  This bug could be
exploited by a malicious local attack to cause a denial-of-service or to
escalate privileges.

* CVE-2022-36280: Out-of-bounds access in vmwgfs driver during cursor snoop.

A failure to validate cursor size data during a snoop operation can
lead to an out-of-bounds memory access.  A malicious local user could
exploit this flaw to escalate their privileges, or to cause a
denial-of-service.

* CVE-2023-23455: Denial-of-service in ATM Virtual Circuit queue operation.

A logic error during a queue operation in the sch_atm driver can result
in an invalid pointer access.  This flaw could be exploited by a local
attacker to cause a denial-of-service.

* CVE-2023-23454: Denial-of-service in CBQ packet scheduling.

When dropping a packet in Class-Based Queueing (CBQ) packet scheduling
algorithm, invalid data may be read. A local user can use this to cause
denial-of-service.

* CVE-2023-0045: Deficiency in existing speculative attack mitigation.

A missing branch predictor barrier leaves systems vulnerable to certain
speculative attacks.  This flaw could be exploited to leak information
from a running system.

* CVE-2022-47929: NULL dereference in traffic control subsystem.

Specially crafted network traffic can cause a NULL pointer dereference
in the network traffic control subsystem.  This flaw could be exploited
by a malicious local user to cause a denial-of-service.

* CVE-2023-0461: Use-after-free in Upper Level Protocol (ULP) subsystem.

Improper handling of sockets entering the LISTEN state can lead to
use-after-free. A local attacker could use this to cause denial-of-service or
execute arbitrary code.

* CVE-2023-0266: Use-after-free in ALSA PCM IOCTL processing.

Missing locks around certain operations can lead to a use-after-free
in the ALSA PCM driver.  This flaw could by exploited by a local
attacker to escalate their privileges.

* CVE-2023-0394: NULL dereference during IPv6 raw frame processing.

An arithmetic error when processing certain IPv6 header information can
lead to a NULL pointer dereference.  A malicious local user could
exploit this flaw to cause a denial-of-service.

* CVE-2022-47520: Out of bounds memory access in WILC1000 wireless driver.

Improper validation of a Robust Security Network element when parsing the
Basic Service Set of a WiFi network could lead to an out-of-bounds memory
access.  A rogue attacker in radio range could use this flaw to cause a
denial-of-service or get remote execution.

* CVE-2022-42328, CVE-2022-42329, XSA-424: Denial-of-service in Xen Netback driver.

A logic flaw in Xen Netback driver when trying to free the SKB of
a dropped packet in some situations could result in a deadlock.
A local user could use this flaw for a denial-of-service.

* CVE-2023-0461: Use-after-free in Upper Level Protocol.

A flaw in ULP when handling sockets entering the LISTEN state in certain
protocols may lead to a user-after-free. A local user could use this
flaw to cause a denial-of-service or elevate privileges on the system.

* CVE-2023-0615: Out-of-bounds memory access in the Virtual Video Test Driver.

Lack of boundary checks when adjusting the composing height could lead to
an out-of-bounds memory access.  A local user with the ability to send
IOCTL to the V4L2 VIVID driver could use this flaw to cause a
denial-of-service or elevate privileges.

* CVE-2023-20938: Use-after-free in the Android Binder deriver.

Lack of input validation in the Android Binder driver when releasing a
transaction buffer could lead to a user-after-free.  A local unprivileged
user could use this flaw to cause a denial-of-service or elevate its
privileges.
