USN-6647-1: Linux kernel vulnerabilities
First published: Wed Feb 21 2024(Updated: )
It was discovered that a race condition existed in the ATM (Asynchronous Transfer Mode) subsystem of the Linux kernel, 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-2023-51780) It was discovered that a race condition existed in the Rose X.25 protocol implementation in the Linux kernel, 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-2023-51782) It was discovered that the netfilter connection tracker for netlink in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2023-7192)
