- Summary
- bpf,perf: Fix invalid prog_array access in perf_event_detach_bpf_prog
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bpf,perf: Fix invalid prog_array access in perf_event_detach_bpf_prog
Syzbot reported [1] crash that happens for following tracing scenario:
-
create tracepoint perf event with attr.inherit=1, attach it to the process and set bpf program to it
-
attached process forks -> chid creates inherited event
the new child event shares the parent's bpf program and tp_event (hence prog_array) which is global for tracepoint
-
exit both process and its child -> release both events
-
first perf_event_detach_bpf_prog call will release tp_event->prog_array and second perf_event_detach_bpf_prog will crash, because tp_event->prog_array is NULL
The fix makes sure the perf_event_detach_bpf_prog checks prog_array is valid before it tries to remove the bpf program from it.
