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

Description A data-race issue around bpf jit limit has been resolved in the Linux kernel. The issue occurs because bpf jit limit can be changed concurrently via sysctl while it is being read. To avoid load-tearing, a paired READ ONCE() is needed because the size of bpf jit limit is long.

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