CVE-2024-43913

Local kernel compromise via stale NVMe controller

Published Aug 26, 2024 · Updated Aug 5, 2026

Use-after-free in Linux 5.19 through 6.10.4 allows local users to corrupt kernel memory through a stale Apple NVMe controller. The Apple NVMe probe frees its devres-backed controller after tag-set setup fails but omits nvme_uninit_ctrl, leaving sysfs and device nodes bound to freed memory. An initialization failure must occur on Apple ANS2 NVMe hardware; subsequent unprivileged reads can disclose kernel data, invoke stale function pointers, or crash the system.
