CVE-2026-53138

A flaw was found in the Linux kernel's AMD display drm/amd/display driver. A malformed VBIOS image can cause unbounded processing loops, leading to an out-of-bounds read. This could result in information disclosure or a system crash...

CVE-2026-53135

A flaw was found in the Linux kernel's drm/amd/display module. A local user could exploit this vulnerability by writing to the sdpmessage debugfs node.

EUVD-2026-39342

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Clamp HDMI HDCP2 rxidlist read to buffer size Why & How During HDCP 2.x repeater authentication over HDMI, the driver reads the sink's RxStatus register and extracts a 10-bit message size field max value 1023. Th...

EUVD-2026-39343

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...

CVE-2026-53136

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Clamp VBIOS HDMI retimer register count to array size Why & How The VBIOS integrated info tables v111 and v21 contain HdmiRegNum and Hdmi6GRegNum fields that are used as loop bounds when copying retimer I2C...
