Description

The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition caused by lack of length check while flashing meta images in the Boot subsystem. An attacker with physical access to device can perform a denial of service attack.

Mitigation
Install updates from vendor's website.
