Description

A flaw was found in the Linux kernel. A local attacker with low privileges could exploit a deadlock vulnerability in the Universal Flash Storage (UFS) host controller driver (ufshcd). This occurs when the error handler and a Command Queue (CQ) event interrupt attempt to acquire the same lock simultaneously. Successful exploitation leads to a system deadlock, causing a Denial of Service (DoS).
