CVE-2022-50721

Kernel panic via qcom-adm error pointer

Published Dec 24, 2025 · Updated Dec 24, 2025

Denial of service in Linux kernel 5.11 through 6.0.2 allows attackers to trigger a kernel panic via unspecified vectors. The qcom-adm prep_slave_sg implementation returns an error pointer instead of NULL, so NAND-controller code treats a failed DMA preparation as successful and later uses the invalid result. Exposure requires the qcom-adm driver and an error on the affected DMA preparation path; the documented consequence is a kernel panic.
