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 OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-0386)

Haowei Yan discovered that a race condition existed in the Layer 2 Tunneling Protocol (L2TP) implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-4129)

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)

It was discovered that the NTFS file system 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-2022-4842)

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)

It was discovered that the Human Interface Device (HID) support driver in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1073)

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)

It was discovered that the NFS implementation in the Linux kernel did not properly handle pending tasks in some situations. A...
