drm/msm/mdp5: Return error code in mdp5_pipe_release when deadlock is detected
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: 0.26% (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 04bef5f1ba8ea6d7c1c8f5f65e0395c62db59cb8, 19964dfb39bda4d7716a71009488f0668ecbcf52, 33dc5aac46e0fad8f5eb193e5906ed0eb6b66ceb.
Low priority for now. Upgrade to Linux Linux 04bef5f1ba8ea6d7c1c8f5f65e0395c62db59cb8, 19964dfb39bda4d7716a71009488f0668ecbcf52, 33dc5aac46e0fad8f5eb193e5906ed0eb6b66ceb or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: drm/msm/mdp5: Return error code in mdp5_pipe_release when deadlock is detected mdp5_get_global_state runs the risk of hitting a -EDEADLK when acquiring the modeset lock, but currently mdp5_pipe_release doesn't check for if an error is returned. Because of this, there is a possibility of mdp5_pipe_release hitting a NULL dereference error. To avoid this, let's have mdp5_pipe_release check if mdp5_get_global_state returns an error and propogate that error. Changes since v1: - Separated declaration and initialization of *new_state to avoid compiler warning - Fixed some spelling mistakes in commit message Changes since v2: - Return 0 in case where hwpipe is NULL as this is considered normal behavior - Added 2nd patch in series to fix a similar NULL dereference issue in mdp5_mixer_release Patchwork: https://patchwork.freedesktop.org/patch/485179/
