The issue allows an unprivileged attacker to force bcc to load compromised Linux headers if kernel headers need to be extracted and are not provided by default. This can occur because bpftrace attempts to load the headers from a temporary directory. Linux distributions that provide kernel headers by default are not affected.

The issue arises when kernel headers need to be extracted, and bcc attempts to load them from a temporary directory. An unprivileged attacker could exploit this to force bcc to load compromised Linux headers. However, Linux distributions that provide kernel headers by default are not affected by default.
