Description

A flaw was found in the Linux kernel's p54 wireless driver. This vulnerability can lead to a denial of service (DoS) or kernel information disclosure. The issue occurs because the firmware parser does not properly validate record lengths before reading component data. A local user capable of loading a crafted firmware file could trigger an out-of-bounds read, causing a system crash or leaking kernel memory.
