[PATCH OLK-6.6] bpf,perf: Fix invalid prog_array access in perf_event_detach_bpf_prog

From: Jiri Olsa <jolsa(a)kernel.org> stable inclusion from stable-v6.6.67 commit c2b6b47662d5f2dfce92e5ffbdcac8229f321d9d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAN1 CVE: CVE-2024-56665 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 978c4486cca5c7b9253d3ab98a88c8e769cb9bbd upstream. 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.
