Summary
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.
