A vulnerability in the Linux kernel's BPF subsystem involving signal tracepoint siginfo arguments has been resolved. The issue arises because the signal_generate and signal_deliver tracepoints declare their info argument as a struct kernel_siginfo pointer, but special values used in signal delivery are not pointers. This can cause a tp_btf program to dereference invalid values, potentially leading to a kernel panic, especially when signal_generate runs from timer interrupt context.
