CVE-2024-57983

Kernel memory corruption via undersized register array

Published Feb 27, 2025 · Updated Aug 5, 2026

Out-of-bounds writes in the TH1520 mailbox driver in Linux 6.13 allow local users to corrupt kernel memory during system suspend. th1520_mbox_suspend_noirq writes four interrupt-mask values into a three-element array, while th1520_mbox_resume_noirq reads the fourth value beyond that array. Reachability requires compatible TH1520 hardware, the affected driver, and a suspend or resume transition; corruption can compromise the kernel or interrupt service.
