kernel did not properly handle certain error conditions, leading to a
double-free. A local attacker could possibly use this to cause a denial of
service (system crash). (CVE-2022-3707)
It was discovered that the infrared transceiver USB driver did not properly
handle USB control messages. A local attacker with physical access could
plug in a specially crafted USB device to cause a denial of service (memory
exhaustion). (CVE-2022-3903)

device to cause a denial of service (system crash). (CVE-2023-1079)
Duoming Zhou discovered that a race condition existed in the infrared
receiver/transceiver driver in the Linux kernel, leading to a use-after-
free vulnerability. A privileged attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2023-1118)
It was discovered that the Traffic-Control Index (TCINDEX) implementation
in the Linux kernel contained a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-1281)
It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
kernel did not properly perform data buffer size validation in some
situations. A physically proximate attacker could use this to craft a
malicious USB device that when inserted, could cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-1380)
Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel
did not properly initialize some data structures. A local attacker could
use this to expose sensitive information (kernel memory). (CVE-2023-1513)
It was discovered that the Xircom PCMCIA network device driver in the Linux
kernel did not properly handle device removal events. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2023-1670)
It was discovered that the Traffic-Control Index (TCINDEX) implementation
in the Linux kernel did not properly perform filter deactivation in some
situations. A local attacker could possibly use this to gain elevated
privileges. Please note that with the fix for this CVE, kernel support for
the TCINDEX classifier has been removed. (CVE-2023-1829)
It was discovered that a race condition existed in the Xen transport layer
implementation for the 9P file system protocol in the Linux kernel, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service (guest crash) or expose sensitive information (guest
kernel memory). (CVE-2023-1859)
Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2
mitigations with prctl syscall were insufficient in some situations. A
local attacker could possibly use this to expose sensitive information.
(CVE-2023-1998)
It was discovered that a use-after-free vulnerability existed in the iSCSI
TCP implementation in the Linux kernel. A local attacker could possibly use
this to cause a denial of service (system crash). (CVE-2023-2162)
It was discovered that the BigBen Interactive Kids' gamepad driver in the
Linux kernel did not properly handle device removal, leading to a use-
after-free vulnerability. A local attacker with physical access co
