CVE-2026-68104: drm/amdgpu: invoke pm_genpd_remove() before freeing genpd

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 08fee493e0261f9e4120a5c8e7e42e8a723574e8, 28c9b3c5dc35cc790d11e26ca3fc6e068be63998, 2e406b86144c1f732eb344f1f1e09043856cfc33; 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 08fee493e0261f9e4120a5c8e7e42e8a723574e8, 28c9b3c5dc35cc790d11e26ca3fc6e068be63998, 2e406b86144c1f732eb344f1f1e09043856cfc33; azl3 kernel 6.6.150.1-1 on Azure Linux 3.0 6.6.150.1-1 or later.
