CVE-2024-36029

Local system crash via suspended controller access

Published May 30, 2024 · Updated May 11, 2026

Denial of service in the Linux kernel allows local users to crash the system by accessing an MMC host-controller LED while it is suspended. The Qualcomm SDHCI driver fails to set host->runtime_suspended, so generic LED handling accesses a suspended controller. Reachability requires a Qualcomm SDHCI MMC controller with its LED interface registered and runtime-suspended; triggering the flaw causes a kernel crash rather than data exposure or modification.
