CVE-2024-50129

Kernel memory corruption via PI array overrun

Published Nov 5, 2024 · Updated May 11, 2026

Out-of-bounds access in Linux kernel PSE-PD 6.10 through 6.11.5 and 6.12-rc1 through 6.12-rc4 allows local users to corrupt kernel memory. The pse_release_pis and of_pse_match_pi loops use an inclusive upper bound and dereference the unallocated pcdev->pi[nr_lines] element. Reachability requires local low-privileged access and a configured PSE controller; exploitation can compromise kernel confidentiality, integrity, and availability.
