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) Lee Jones discovered that a use-after-free vulnerability existed in the Bluetooth implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-20566) It was discovered that the ISDN implementation of the Linux kernel contained a use-after-free vulnerability. A privileged user could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3565) It was discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel contained a reference counting error. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-36879) It was discovered that the USB monitoring (usbmon) component in the Linux kernel did not properly set permissions on memory mapped in to user space processes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43750) It was discovered that the NFSD implementation in the Linux kernel contained a use-after-free vulnerability. A remote attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-4379) It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate offsets, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash). (CVE-2022-47520) 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)
