Description

A flaw was found in the Linux kernel's comedi: me4000 driver. The me4000_xilinx_download() function fails to validate the length of the firmware data stream, trusting the value provided in the firmware header. A local attacker could exploit this by providing a specially crafted firmware image, leading to a buffer overrun. This could result in a denial of service (DoS) or potentially other system instabilities.

Mitigation
