CVE-2026-53138

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Bound VBIOS record-chain walk loops Why & How All record-chain walk loops in biosparser.c and biosparser2.c use for;; and only terminate on a 0xFF recordtype sentinel or zero recordsize. A malformed VBIOS image...

CVE-2026-53138

The CVE affects the Linux kernel’s drm/amd/display path. A malformed VBIOS image could cause unbounded iteration during probe due to for(;;) record-chain walks in bios_parser.c/bios_parser2.c, terminating only on a 0xFF sentinel or a zero record_size. In worst cases, this could loop hundreds of t...

CVE-2026-53136

The CVE pertains to the Linux kernel driver drm/amd/display. A malformed VBIOS can set HdmiRegNum/Hdmi6GRegNum to values up to 255, used as loop bounds when copying retimer I2C settings into fixed-size arrays, causing an out-of-bounds heap write during driver probe. The fix clamps each register c...
