cve 2026 68235

CVE-2026-68235 is a Linux kernel issue that crashes the AMDGPU display driver on older AMD DCE8-era hardware when a second monitor is connected via DisplayPort Multi-Stream Transport (MST). The affected code resides in the Linux drm/amd/display driver, not in Windows, the AMD Software: Adrenalin Edition Windows driver, or the Windows display stack. The National Vulnerability Database entry was published on August 11, 2026, but was initially unavailable due to a Cloudflare 502 error, leaving no CVSS score or affected kernel details. This tag covers the CVE's impact, the missing NVD data, and the distinction from Windows-specific driver issues.
