CVE-2025-22107

Kernel crash via out-of-bounds table deletion read

Published Apr 16, 2025 · Updated Sep 8, 2026

Out-of-bounds read in Linux's SJA1105 DSA driver allows local users to crash the kernel when a table deletion reaches unmapped memory. The deletion function invokes memmove for the final element and copies the original count rather than one fewer element, reading beyond the table. Reachability requires local low-privileged access and the SJA1105 DSA driver; the bounded reported consequence is a kernel crash.
