USN-8962-1: Linux kernel (Azure CVM) vulnerabilities

Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux kernel, leading to use-after-free vulnerabilities. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1205)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems:
