About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
Octeontx2-af: Add proper checks for fwdata
firmware populates MAC address, link modes (supported, advertised) and EEPROM data in shared firmware structure which kernel access via MAC block(CGX/RPM).
Accessing fwdata, on boards booted with out MAC block leading to kernel panics.
