CVE-2024-36016

Kernel memory corruption via stale frame length

Published May 29, 2024 · Updated Aug 5, 2026

Out-of-bounds access in the Linux kernel n_gsm line discipline allows local users to corrupt kernel memory through crafted GSM frames. gsm0_receive() retains stale state and length values across basic-to-advanced mode changes, then writes beyond gsm->buf when subsequent data makes the count exceed the old length. Exploitation requires local line-discipline configuration and control of the peer frame sequence; the bounded consequence is kernel-memory disclosure or corruption and a possible host crash.
