TLDRVuln - Cybersecurity Vulnerabilities Made Simple

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.
