| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A reference count leak issue exists in the Linux kernel, specifically in the drm/amd/amdgpu/amdgpu cs module. The problem occurs in the
amdgpu cs fence to handle ioctl() function when the info->in.what value falls into the default case, causing the function to return an error code without decrementing the reference count of a dma fence object. This can result in reference count leaks.Recommendations
For the affected Linux kernel version, apply the fix by decreasing the reference count of the specific object before returning the error code in the
amdgpu cs fence to handle ioctl() function.Exploit
