CVE-2022-48704: drm/radeon: add a force flush to delay work when radeon

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.23% (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 16cb367daa446923d82e332537f446a4cc784b40, 4e25e8f27fdbdc6fd55cc572a9939bf24500b9e8, 5a7a5b2edac4b05abd744eeaebda46d9dacd952d.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 16cb367daa446923d82e332537f446a4cc784b40, 4e25e8f27fdbdc6fd55cc572a9939bf24500b9e8, 5a7a5b2edac4b05abd744eeaebda46d9dacd952d or later.

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: add a force flush to delay work when radeon Although radeon card fence and wait for gpu to finish processing current batch rings, there is still a corner case that radeon lockup work queue may not be fully flushed, and meanwhile the radeon_suspend_kms() function has called pci_set_power_state() to put device in D3hot state. Per PCI spec rev 4.0 on 5.3.1.4.1 D3hot State. > Configuration and Message requests are the only TLPs accepted by a Function in > the D3hot state. All other received Requests must be handled as Unsupported Requests, > and all received Completions may optionally be handled as Unexpected Completions.
