USN-5913-1: Linux kernel (OEM) vulnerabilities

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)
