CVE-2026-46188

A flaw was found in the Linux kernel. Specifically, within the octeonepvf driver, the octepvfoqprocessrx function fails to check for a NULL return value from napibuildskb during memory allocation. This oversight can lead to a NULL pointer dereference, allowing a local attacker to potentially caus...
