CVE-2024-53212

Kernel warning via stale netlink bounds check

Published Dec 27, 2024 · Updated May 11, 2026

Improper validation in Linux kernel 6.10 through 6.11.10 and 6.12 through 6.12.1 allows local users to trigger a kernel warning. netlink_ack_tlv_fill checks a bad-attribute pointer against skb->data after the initiating message has been pulled, rather than against the stable netlink header. The path requires a later dump failure after the receive queue is filled; published evidence demonstrates a warning but does not report a panic, reboot, data loss, or code execution.
