CVE-2022-50069

Kernel crash via unchecked BPF instruction pointer

Published Jun 18, 2025 · Updated May 11, 2026

NULL pointer dereference in Linux kernel 5.14 through 5.15.62 and 5.16 through 5.19.3 allows local users to crash the kernel. bpf_prog_load passes an attacker-controlled kernel-space insns pointer to copy_from_bpfptr, whose backing sockptr operation performs memcpy without validating the address. Reachability requires a verified eBPF syscall program; dereferencing an invalid address causes an unhandleable page fault and kernel oops.
