CVE-2024-50132

Kernel crash via trace-probe argument miscount

Published Nov 5, 2024 · Updated Aug 5, 2026

NULL pointer dereference in Linux kernel 6.9 through 6.11.5 allows local users to crash the kernel via oversized trace-probe arguments. Trace-probe creation records nr_args before truncating fetch arguments to MAX_TRACE_ARGS, so __set_print_fmt reads uninitialized entries beyond the 128 initialized slots. A local low-privileged user must be able to configure a trace probe; successful triggering causes a kernel oops and service interruption.
