CVE-2022-50721

A flaw was found in the Linux kernel’s dmaengine qcom-adm implementation where the function prep_slave_sg did not adhere to the documented error return convention. On error, it returned an error pointer instead of NULL, which can cause consumers that check only for non-NULL to assume success and later dereference an invalid pointer. Under certain workloads (e.g., with the nandc driver), this can lead to a kernel panic, resulting in an availability impact.
