Description OSIDB Bzimport 2026-09-24 16:43:00 UTC
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.
