drm display

About this tag
The drm display tag on WindowsForum.com covers security vulnerabilities and fixes in the Linux kernel's Direct Rendering Manager (DRM) display subsystem, particularly the AMDGPU driver. Discussions focus on CVEs such as CVE-2025-38091, CVE-2025-68286, CVE-2024-47661, CVE-2024-49920, CVE-2024-49972, CVE-2024-46730, and CVE-2024-42064. Common themes include null pointer dereferences, integer overflows, allocation failures, and array index errors that can cause kernel crashes or denial-of-service. The content details upstream patches, operational impacts, and mitigation strategies for affected Linux systems. While the tag is Linux-specific, it is relevant to Windows users running Linux virtual machines or dual-boot setups.

    CVE-2025-38091: Linux AMD DRM DML21 NULL Plane ID Guard Fix

    A subtle missing check in the Linux kernel’s AMD DRM display code has been cataloged as CVE-2025-38091 and corrected upstream; the defect can produce kernel warnings and, in some circumstances, a local denial-of-service by allowing the display stack to hit an oops when querying a plane...

    CVE-2025-68286: Linux AMDGPU NULL pointer crash patched upstream in DRM

    A targeted NULL‑check omission in the Linux kernel’s AMD display driver has been cataloged as CVE‑2025‑68286 and patched upstream — but the operational impact, exposure model, and the path to mitigation deserve careful attention from desktop users, cloud operators, and embedded vendors alike...

    CVE-2024-47661: Linux AMD DRM Display Fix Prevents 32-bit to 8-bit Overflow

    A small arithmetic oversight in the Linux kernel's AMD display stack—tracked as CVE-2024-47661—was patched with a surgical code change that prevents an integer overflow when a 32-bit value is assigned into an 8-bit field; while the flaw is not remotely exploitable, it carries a clear...

    Linux Kernel AMD Display Patch CVE-2024-49920 Null Pointer Safety

    The Linux kernel’s AMD display subsystem received a targeted safety fix for CVE‑2024‑49920: a set of null‑pointer checks added to the DRM/AMD display code to prevent repeated dereferences of possibly NULL objects — a class of bugs that can trigger kernel crashes and sustained denial‑of‑service...

    CVE-2024-49972: AMD DRM DML Allocation Fix in Linux Kernel

    A Linux kernel vulnerability in the AMD DRM/display stack — tracked as CVE-2024-49972 — can leave driver state in an inconsistent condition when a Display Mode Library (DML) allocation fails, causing driver instability and a local denial-of-service until the host is rebooted or patched. The flaw...

    Linux Kernel CVE-2024-46730: AMD DRM DoS Fix and Mitigations

    A recently disclosed Linux-kernel vulnerability, tracked as CVE-2024-46730, affects the AMD DRM display subsystem (drivers/gpu/drm/amdgpu — the drm/amd/display code path) and can cause a deterministic denial-of-service by using a negative array index (tg_inst == -1) when the driver assumes at...

    CVE-2024-42064: AMD DRM Skip Pipe Fix Prevents Kernel Crash

    In the Linux kernel security landscape, a medium‑severity vulnerability tracked as CVE‑2024‑42064 was disclosed affecting the AMD DRM display driver: a defect in drm/amd/display that can cause the driver to crash when a pipe index (pipe idx) is not set properly, and the upstream remedy is to...
