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-2022-45886, CVE-2022-45919)

Hyunwoo Kim discovered that the Technotrend/Hauppauge USB DEC 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-2022-45887)

It was discovered that the NTFS file system implementation in the Linux
kernel did not properly validate MFT flags in certain situations. An
attacker could use this to construct a malicious NTFS image that, when
mounted and operated on, could cause a denial of service (system crash).
(CVE-2022-48425)

It was discovered that the IPv6 implementation in the Linux kernel
contained a high rate of hash collisions in connection lookup table. A
remote attacker could use this to cause a denial of service (excessive CPU
consumption). (CVE-2023-1206)

Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD
processors utilising speculative execution and branch prediction may allow
unauthorised memory reads via a speculative side-channel attack. A local
attacker could use this to expose sensitive information, including kernel
memory. (CVE-2023-20569)

Jana Hofmann, Emanuele Vannacci, Cedric Fournet, Boris Kopf, and Oleksii
Oleksenko discovered that some AMD processors could leak stale data from
division operations in certain situations. A local attacker could possibly
use this to expose sensitive information. (CVE-2023-20588)

It was discovered that the ARM64 KVM implementation in the Linux kernel did
not properly restrict hypervisor memory access. An attacker in a guest VM
could use this to execute arbitrary code in the host OS. (CVE-2023-21264)

It was discovered that the IPv6 RPL protocol implementation in the Linux
kernel did not properly handle user-supplied data. A remote attacker could
use this to cause a denial of service (system crash). (CVE-2023-2156)

Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in
the Linux kernel contained a race condition, leading to a null pointer
dereference vulnerability. A local attacker could use this to cause a
denial of service (system crash). (CVE-2023-31083)

Yang Lan discovered that the GFS2 file system implementation in the Linux
kernel could attempt to dereference a null pointer in some situations. An
attacker could use this to construct a malicious GFS2 image that, when
mounted and operated on, could cause a denial of service (system crash).
(CVE-2023-3212)

Ross Lagerwall discovered that the Xen netback backend driver in the Linux
kernel did not properly handle certain unusual packets from a
paravirtualized network frontend, leading to a ... [Please see the references for more information on the vulnerabilities]");
