Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: harden FRU PIA parsing with bounded helpers Replace the open-coded TLV walk with fru_pia_advance() and fru_pia_copy_field() helpers that bound every read by the actual EEPROM data length, preventing out-of-bounds reads on truncated or malformed FRU data.
