CVE-2024-56602

Kernel compromise via dangling IEEE 802.15.4 socket pointer

Published Dec 27, 2024 · Updated Aug 5, 2026

Use-after-free in Linux 2.6.31 and later allows local users to corrupt kernel memory through a failed IEEE 802.15.4 socket creation. sock_init_data() stores the allocated sk pointer in the supplied sock before ieee802154_create() completes, and a later error frees sk without clearing that reference. Triggering requires low-privileged local access and a post-initialization creation failure; reuse of the dangling pointer can compromise kernel confidentiality, integrity, and availability.
