CVE-2022-49137

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A reference count leak occurs in the amdgpu cs fence to handle ioctl() function within the AMD GPU driver. The issue is triggered during an error path when the info->in.what variable falls into the default case, causing the function to return -EINVAL without decrementing the reference count of a dma fence object previously increased by amdgpu cs get fence(). This failure to manage the reference count can lead to memory leaks and may allow an attacker to cause a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
