CVE-2024-44982: drm/msm/dpu: cleanup FB if dpu_format_populate_layout fails

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: 0.24% (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 02193c70723118889281f75b88722b26b58bf4ae, 7ecf85542169012765e4c2817cd3be6c2e009962, 9b8b65211a880af8fe8330a101e1e239a2d4008f; Azure Linux 3.0 ARM 6.6.51.1-5; Azure Linux 3.0 x64 6.6.51.1-5.

Low priority for now. Upgrade to Linux Linux 02193c70723118889281f75b88722b26b58bf4ae, 7ecf85542169012765e4c2817cd3be6c2e009962, 9b8b65211a880af8fe8330a101e1e239a2d4008f; Azure Linux 3.0 ARM 6.6.51.1-5; Azure Linux 3.0 x64 6.6.51.1-5 or later.

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: cleanup FB if dpu_format_populate_layout fails If the dpu_format_populate_layout() fails, then FB is prepared, but not cleaned up.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
