Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue exists in the drm/panthor subsystem of the Linux kernel, specifically within the GROUP CREATE ioctl function. The issue arises from accessing a pointer to a group after it has been stored in an Xarray. A malicious user could potentially exploit this by predicting a group handle and attempting to call the GROUP DESTROY ioctl concurrently with the GROUP CREATE ioctl. The fix involves adding a mark to the group pool Xarray entry immediately before returning from the GROUP CREATE ioctl function, which is then checked by all ioctls specifying the group handle. This prevents userspace from deleting a group that hasn't been properly marked.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
