- Summary
- bpf: Fix re-attachment branch in bpf_tracing_prog_attach
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix re-attachment branch in bpftracingprog_attach
The following case can cause a crash due to missing attach_btf:
1) load rawtp program 2) load fentry program with rawtp as targetfd 3) create tracing link for fentry program with targetfd = 0 4) repeat 3
In the end we have:
- prog->aux->dst_trampoline == NULL
- tgtprog == NULL (because we did not provide targetfd to link_create)
- prog->aux->attachbtf == NULL (the program was loaded with attachprog_fd=X)
the program was loaded for tgt_prog but we have no way to find out which one
