A flaw was found in BPFtrace. This issue occurs when extracting kernel headers, it tries to load them from a temporary directory.

Description TEJ RATHI 2024-03-11 14:15:51 UTC 
If kernel headers need to be extracted, bpftrace will attempt to load them from a temporary directory. An unprivileged attacker could use this to force bcc to load compromised linux headers. Linux distributions which provide kernel headers by default are not affected by default.
