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)

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)

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)

It was discovered that the KSMBD implementation in the Linux kernel did not
properly validate buffer sizes in certain operations, leading to an integer
underflow and out-of-bounds read vulnerability. A remote attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2023-38427)

Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel
did not properly validate packet header sizes in certain situations,
leading to an out-of-bounds read vulnerability. A remote attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2023-38431)

Andy Nguyen discovered that the KVM implementation for AMD processors in
the Linux kernel with Secure Encrypted Virtualization (SEV) contained a
race condition when accessing the GHCB page. A local attacker in a SEV
guest VM could possibly use this to cause a denial of service (host ... [Please see the references for more information on the vulnerabilities]");
