Summary
It was discovered that the Upper Level Protocol (ULP) subsystem in the
Linux kernel did not properly handle sockets entering the LISTEN state in
certain protocols, leading to 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-2023-0461)
It was discovered that the System V IPC implementation in the Linux kernel
did not properly handle large shared memory counts. A local attacker could
use this to cause a denial of service (memory exhaustion). (CVE-2021-3669)
It was discovered that a use-after-free vulnerability existed in the SGI
GRU driver in the Linux kernel. A local attacker could possibly use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3424)
It was discovered that a race condition existed in the Kernel Connection
Multiplexor (KCM) socket implementation in the Linux kernel when releasing
sockets in certain situations. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-3521)
It was discovered that the Netronome Ethernet driver 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-2022-3545)
It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
kernel did not properly perform bounds checking 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 execute arbitrary code. (CVE-2022-3628)
Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux
kernel contained an out-of-bounds write vulnerability. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2022-36280)
It was discovered that a use-after-free vulnerability existed in the
Bluetooth stack in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3640)
Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not
properly perform reference counting in some situations, leading to 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-2022-41218)
It was discovered that a race condition existed in the Xen network backend
driver in the Linux kernel when handling dropped packets in certain
circumstances. An attacker could use this to cause a denial of service
(kernel deadlock). (CVE-2022-42328, CVE-2022-42329)
Tamás Koczka discovered that the Bluetooth L2CAP implementation in the
Linux kernel did not properly initialize memory in some situations. A
physically proximate attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-42895)
It was discovered that the network queuing discipline implementation in the
Linux kernel contained a null pointer dereference in some situations. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2022-47929)
José Oliveira and Rodrigo Branco discovered that the prctl syscall
implementation in the Linux kernel did not properly protect against
indirect branch prediction attacks in some situations. A local attacker
could possibly use this to expose sensitive information. (CVE-2023-0045)
It was discovered that a use-after-free vulnerability existed in the
Advanced Linux Sound Architecture (ALSA) subsystem. A local attacker could
use this to cause a denial of service (system crash). (CVE-2023-0266)
Kyle Zeng discovered that the IPv6 implementation in the Linux kernel
contained a NULL pointer dereference vulnerability in certain situations. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-0394)
Kyle Zeng discovered that the ATM VC queuing discipline implementation in
the Linux kernel contained a type confusion vulnerability in some
situations. An attacker could use this to cause a denial of service (system
crash). (CVE-2023-23455)
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)
