CVE-2024-21944

CVE-2024-21944 maps to an AMD SEV-SNP/ASP issue where SPD metadata can be improperly validated. Research show BadRAM-style exploits that can cause a memory module to misreport size, enabling a local attacker with ring0 or physical access to overwrite guest memory and compromise guest data integri...

Dell PowerEdge: CVE-2024-21944: DSA-2024-404: Security Update for Dell AMD-based PowerEdge Server Vulnerabilities

Improper input validation for DIMM serial presence detect SPD metadata could allow an attacker with physical access, ring0 access on a system with a non-compliant DIMM, or control over the Root of Trust for BIOS update, to potentially overwrite guest memory resulting in loss of guest data integri...

SUSE CVE-2026-46245

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix dclink NULL handling in HPD init amdgpudmhpdinit may see connectors without a valid dclink. The code already checks dclink for the polling decision, but later unconditionally dereferences it when setting up H...

CVE-2026-46245

A flaw was found in the Linux kernel's AMD GPU display driver. The amdgpudmhpdinit function, responsible for Hot-Plug Detect HPD initialization, may attempt to dereference a null dclink when handling certain connectors. This unconditional dereference can lead to a system crash, allowing a local...

CVE-2026-46245

CVE-2026-46245 affects the AMDGPU display driver in the Linux kernel. The vulnerability arises in amdgpu_dm_hpd_init() where a NULL dc_link could be dereferenced while setting up HPD interrupts, despite an earlier check for polling decisions. The provided patch assigns dc_link early and skips con...
