Details

Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did
not properly perform permissions checks when handling HCI sockets. A
physically proximate attacker could use this to cause a denial of service
(bluetooth communication). (CVE-2023-2002)

Zheng Zhang discovered that the device-mapper implementation in the Linux
kernel did not properly handle locking during table_clear() operations. A
local attacker could use this to cause a denial of service (kernel
deadlock). (CVE-2023-2269)

It was discovered that the Ricoh R5C592 MemoryStick card reader driver in
the Linux kernel contained a race condition during module unload, 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-2023-3141)

Quentin Minster discovered that the KSMBD implementation in the Linux
kernel did not properly validate pointers in some situations, leading to a
null pointer dereference vulnerability. A remote attacker could use this to
cause a denial of service (system crash). (CVE-2023-32248)

Quentin Minster discovered that a race condition existed in the KSMBD
implementation in the Linux kernel, leading to a use-after-free
vulnerability. A remote attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2023-32254)

It was discovered that the kernel->user space relay implementation in the
Linux kernel did not properly perform certain buffer calculations, leading
to an out-of-bounds read vulnerability. A local attacker could use this to
cause a denial of service (system crash) or expose sensitive information
(kernel memory). (CVE-2023-3268)

It was discovered that the QCOM CPUFreq HW driver in the Linux kernel on
ARM processors did not properly handle device unbind. A local attacker
could use this to cause a denial of service (system crash). (CVE-2023-3312)

It was discovered that the MediaTek MT7921E (PCIe) WiFi driver in the Linux
kernel contained a use-after-free vulnerability when querying the firmware
features of the device. A local attacker could use this to cause a denial
of service (system crash). (CVE-2023-3317)

It was discovered that the video4linux driver for Philips based TV cards in
the Linux kernel contained a race condition during device removal, 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-2023-35823)

It was discovered that the SDMC DM1105 PCI device driver in the Linux
kernel contained a race condition during device removal, 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-2023-35824)

It was discovered that the Allwinner Cedar video engine driver in the Linux
kernel contained a race condition during device removal, 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-2023-35826)

It was discovered that the Renesas USB controller driver in the Linux
kernel contained a race condition during device removal, 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-2023-35828)

It was discovered that the Rockchip Video Decoder IP driver in the Linux
kernel contained a race condition during device removal, 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-2023-35829)
