This allows a stack-based buffer overflow that could lead to a potential Remote Code Execution on the targeted device

CRITICAL 9.8EPSS 1.14%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

During the retrofit validation process, the firmware doesn't properly check the boundaries while copying some attributes to check. This allows a stack-based buffer overflow that could lead to a potential Remote Code Execution on the targeted device
