In the Linux kernel, the following vulnerability has been resolved:
bpf: Skip task with pid=1 in send_signal_common()
The following kernel panic can be triggered when a task with pid=1 attaches
a prog that attempts to send killing signal to itself, also see [1] for more
details:
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
CPU: 3 PID: 1 Comm: systemd Not tainted 6.1.0-09652-g59fe41b5255f #148

So skip task with pid=1 in bpf_send_signal_common() to avoid the panic.
