CVE-2023-52576

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a use-after-free vulnerability in the Linux kernel, specifically in the ima free kexec buffer() function.

With KASAN or KFENCE, this use-after-free will result in a BUG from the idle task and a subsequent kernel panic. The vulnerability can be exploited by a remote attacker to cause a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
