CVE-2026-68106: drm/amdgpu: fix division by zero with invalid uvd dimensions
Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.13% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 004d0453cfef16f056cb7b8bc04f69f19cf9df32, 00ee64910ecf748cc15b23bbcbea472c203ec1e8, 0c01c811be47e6b146552dd59bfedbea8f09b8f4; azl3 kernel 6.6.150.1-1 on Azure Linux 3.0 6.6.150.1-1.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to Linux Linux 004d0453cfef16f056cb7b8bc04f69f19cf9df32, 00ee64910ecf748cc15b23bbcbea472c203ec1e8, 0c01c811be47e6b146552dd59bfedbea8f09b8f4; azl3 kernel 6.6.150.1-1 on Azure Linux 3.0 6.6.150.1-1 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix division by zero with invalid uvd dimensions When width or height is less than 16, width_in_mb or height_in_mb becomes 0, leading to fs_in_mb being 0. This causes a division by zero when calculating num_dpb_buffer in H264 and H264 Perf decode paths. Add validation to reject frames with width < 16 or height < 16 before performing any calculations that depend on these values. V2: Format change - move up all vaiable definitions. V3: Use warn_once to avoid spam. (cherry picked from commit 3e41d26c70b0a459d041cc19482a226c4b7423cb)
