It is attacked with local access, in an operating system.

Am I affected by CVE-2026-97928?

Check whether you run Linux Foundation Linux kernel at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

CVE-2026-97928: Linux kernel amdgpu TTM buffer mapping denial of service in GFX11

CVE-2026-97928 · Severity: info · Published 2026-09-25

A bug in the Linux kernel's AMD GPU driver causes the GPU's SDMA (System DMA) engine to become wedged (locked up) on GFX11 graphics cards such as AMD Navi33. The issue occurs during memory clearing operations when unnecessary flush commands are issued to the GPU, resulting in a denial of service where the device stops responding.

Vendors: Linux Foundation.

Technical details

The vulnerability exists in amdgpu_ttm_map_buffer() within the TTM (Translation Table Maps) subsystem of the AMD GPU driver. When accessing VRAM directly (without a GART window), the code incorrectly forces a VMID 0 TLB flush that causes a spurious SDMA flush on GFX11 hardware, wedging the SDMA engine. The fix adds a vm_needs_flush output parameter to distinguish between direct MC address access (which needs no flush) and GART window access (which requires the flush).
