CVE-2024-50103

Kernel crash via unchecked allocation failure

Published Nov 5, 2024 · Updated May 11, 2026

NULL pointer dereference in Qualcomm LPASS ASoC support in Linux allows local users to crash the kernel during device probing. asoc_qcom_lpass_cpu_platform_probe() dereferences the allocation returned by devm_kzalloc() without checking whether allocation failed. Exploitation requires low-privileged local access and a Qualcomm LPASS device probe under allocation failure, causing a kernel crash without reported data exposure or modification.
