NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by RHEL.

In the Linux kernel, the following vulnerability has been resolved:

drm: Do not allow userspace to trigger kernel warnings in drm_gem_change_handle_ioctl()

Since GEM bo handles are u32 in the uapi and the internal implementation uses idr_alloc() which uses int ranges, passing a new handle larger than INT_MAX trivially triggers a kernel warning:

idr_alloc(): ... if (WARN_ON_ONCE(start < 0)) return -EINVAL; ...

Fix it by rejecting new handles above INT_MAX and at the same time make the end limit calculation more obvious by moving into int domain.
