CVE-2024-27005

Kernel memory corruption via unsynchronized interconnect request list

Published May 1, 2024 · Updated Aug 5, 2026

Race condition in the Linux kernel allows local users to corrupt kernel memory through concurrent interconnect requests. The icc_set_bw() path iterates icc_node::req_list under icc_bw_lock while of_icc_get() and icc_put() can add or remove entries under only icc_lock, leaving the iterator with an invalid pointer. A low-privileged local user must repeatedly drive an interconnect-backed device path; a successful race exposes kernel memory, changes protected state, or crashes the host.
