CVE-2022-42328 [MEDIUM] Linux kernel (GCP) vulnerabilities
Title: Linux kernel (GCP) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
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)
It was discovered that an out-of-bounds write vulnerability existed in the
Video for Linux 2 (V4L2) implementation in the Linux kernel. A local
