CVE-2022-50540

Kernel panic via pointer-size comparison in slave_config

Published Oct 7, 2025 · Updated Oct 7, 2025

Denial of service in the Linux kernel 5.17 through 5.19.16 and 6.0 through 6.0.2 allows local users to trigger a kernel panic. The adm_slave_config function compares peripheral_size with the size of a config pointer, so it skips copying the supplied CRCI value when a full configuration structure is provided. The fault is reachable on systems using the Qualcomm ADM DMA driver with a slave configuration that supplies the extended peripheral data.
