CVE-2026-23070

Estado: ModificadaMedia (5.5)—

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.
