CVE-2024-47695

Out-of-bounds kernel access during connection cleanup

Published Oct 21, 2024 · Updated Aug 5, 2026

Out-of-bounds access in the Linux kernel allows local users to access kernel memory during failed RTRS client connection setup. The init_conns() error path leaves cid equal to con_num after create_con() or create_cm() fails, so its cleanup loop indexes one connection beyond the allocated array. Reachability requires the RTRS client path and a connection-creation failure; the public record does not specify whether the access reads or writes memory or report a concrete outcome.
