CVE-2024-35837

Kernel panic via uncleared mvpp2 pool state

Published May 17, 2024 · Updated May 11, 2026

Denial of service in affected Linux mvpp2 network drivers allows local users to trigger a kernel panic after a kexec reboot. The mvpp2_bm_init path reuses buffer-manager pools whose hardware registers retain stale values across kexec instead of draining and stopping each pool before initialization. Exposure requires an affected kernel on Marvell mvpp2 hardware and a kexec reboot; the reported consequence is a system crash, not data access or modification.
