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.

This causes problems for bpftrace which is built against bcc and the system libbpf. The resulting version skew between the vendored and system versions of libbpf resulting in a SEGV whenever bpftrace is used. Although --help and -l (list probe points) work OK that is because they do not actually use BPF! Anything that does use BPF will crash immediately, including bpftrace --info and simple one-liners such as: ~# bpftrace -e 't:raw_syscalls:sys_exit { printf("%s", comm); }' Attaching 1 probe... Segmentation fault Note that this issue is very closely related to similar problems compiling bpftrace against mixed headers from the two libbpf versions.

Unfortunately it is not currently possible to de-vendor libbpf because bcc does not build. Fix this with brute force and ignorance... and in a seperate patch so this can be treated as an explanation of the problem and ripped out in favour of the right fix.
