 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7f We can reproduce the warning by
 following the steps below: 1. echo 8 >> set_event_notrace_pid. Let tr->filtered_pids owns one pid and
 register sched_switch tracepoint. 2. echo ' ' >> set_event_pid, and perform fault injection during chunk
 allocation of trace_pid_list_alloc. Let pid_list with no pid and assign to tr->filtered_pids. 3. echo ' '
 >> set_event_pid. Let pid_list is NULL and assign to tr->filtered_pids. 4. echo 9 >> set_event_pid, will
 trigger the double register sched_switch tracepoint warning. The reason is that syzkaller injects a fault
 into the chunk allocation in trace_pid_list_alloc, causing a failure in trace_pid_list_set, which may
 trigger double register of the same tracepoint. This only occurs when the system is about to crash, but to
 suppress this warning, let's add failure handling logic to trace_pid_list_set. (CVE-2025-39914)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
