Background
The drm/msm/mdp5 package is a component of the Linux Kernel that provides support for display and graphics functionality on devices using Qualcomm Adreno GPUs. It includes the mdp5_pipe_release function, which is responsible for releasing resources associated with a display pipeline. However, a vulnerability has been discovered in this function that can lead to a deadlock condition when certain conditions are met.
Vulnerability Detail
The vulnerability in the mdp5_pipe_release function allows for a deadlock to occur under specific circumstances. When this happens, the function fails to return an error code, which can result in a denial of service (DoS) condition. An attacker could potentially exploit this vulnerability to cause a system to become unresponsive or crash. The vulnerability was introduced in version v4.18 of the Linux Kernel and has been fixed in version v5.18.3.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary workaround, users can disable the affected functionality by modifying the system configuration. This can be done by adding the following line to the kernel command line during boot: mdp5.disable=1. However, it is important to note that this workaround will disable the display and graphics functionality provided by the drm/msm/mdp5 package.
Conclusion
In conclusion, the vulnerability in the drm/msm/mdp5 package can lead to a deadlock condition, resulting in a denial of service (DoS) situation. It is recommended to update the Linux Kernel to version v5.18.3 or later to fix this vulnerability. A temporary workaround is available by disabling the affected functionality, but this will also disable the display and graphics functionality provided by the package.
