USN-6249-1

Ruihan Li discovered that the memory management subsystem in the Linux kernel contained a race condition when accessing VMAs in certain conditions, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-3269)
