CVE-2026-64163

CVE-2026-64163 targets the Linux kernel kprobes test module. The issue arises from leftover data in kprobes/kretprobes between test runs, causing register_kprobe to fail with -22 and potentially crashing the kernel. The fix moves all kprobe/kretprobe cleanup into kprobes_test_init, which runs bef...
