CVE-2024-50110

Kernel-memory disclosure via uninitialized XFRM padding

Published Nov 5, 2024 · Updated May 11, 2026

Information disclosure in the Linux XFRM subsystem allows local users to read uninitialized kernel memory through Netlink state dumps. copy_to_user_state_extra copies whole XFRM algorithm structures to user space, including padding bytes that were never initialized. Low-privileged local access is required, and the demonstrated consequence is limited to disclosure of residual kernel data.
