CVE-2024-53165

Kernel memory corruption via stale interrupt-controller entry

Published Dec 27, 2024 · Updated Aug 5, 2026

Use-after-free in the Linux SuperH interrupt controller allows local users to read or corrupt kernel memory after an early-boot error. register_intc_controller() adds d to intc_list before initialization finishes, then frees d after an allocation or mapping failure without removing the list entry. A vulnerable SuperH kernel with CONFIG_SH_INTC must encounter that early-boot failure; later traversal can disclose or corrupt kernel memory or panic the host.
