Details

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 Integrity Measurement Architecture (IMA)
implementation in the Linux kernel did not properly enforce policy in
certain conditions. A privileged attacker could use this to bypass Kernel
lockdown restrictions. (CVE-2022-21505)

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)

It was discovered that a race condition existed in the SMSC UFX USB driver
implementation in the Linux kernel, leading to a use-after-free
vulnerability. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-41849)

Gerald Lee discovered that the USB Gadget file system implementation in the
Linux kernel contained a race condition, leading to a use-after-free
vulnerability in some situations. A local attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-4382)

It was discovered that a memory leak existed in the SCTP protocol
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (memory exhaustion). (CVE-2023-1074)

Mingi Cho discovered that the netfilter subsystem in the Linux kernel did
not properly initialize a data structure, leading to a null pointer
dereference vulnerability. An attacker could use this to cause a denial of
service (system crash). (CVE-2023-1095)

It was discovered that the RNDIS USB driver in the Linux kernel contained
an integer overflow vulnerability. A local attacker with physical access
could plug in a malicious USB device to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2023-23559)

It was discovered that the NTFS file system implementation in the Linux
kernel did not properly validate attributes in certain situations, leading
to an out-of-bounds read vulnerability. A local attacker could possibly use
this to expose sensitive information (kernel memory). (CVE-2023-26607)

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)
