**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A issue in the Linux kernel has been identified where the `mdp5 mixer release` function does not check for an error return when acquiring the modeset lock, potentially leading to a NULL dereference error. The `mdp5 get global state` function may return `-EDEADLK` when a deadlock is detected. To prevent this, the `mdp5 mixer release` function should be modified to check for and propagate any error returned. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability in the Linux kernel has been identified, where the `mdp5 pipe release` function does not check for errors returned by `mdp5 get global state`, potentially leading to a NULL dereference error. This issue arises when `mdp5 get global state` attempts to acquire the modeset lock and encounters a deadlock, resulting in a -EDEADLK error. To mitigate this, the `mdp5 pipe release` function has been modified to propagate any errors returned by `mdp5 get global state`. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
