Overview

CVE-2022-50417 is a high-severity vulnerability. It was published on September 18, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

drm/panfrost: Fix GEM handle creation ref-counting

panfrost_gem_create_with_handle() previously returned a BO but with the

only reference being from the handle, which user space could in theory

guess and release, causing a use-after-free. Additionally if the call to

panfrost_gem_mapping_get() in panfrost_ioctl_create_bo() failed then

a(nother) reference on the BO was dropped.

The _create_with_handle() is a problematic pattern, so ditch it and

instead create the handle in panfrost_ioctl_create_bo(). If the call to

panfrost_gem_mapping_get() fails then this means that user space has

indeed gone behind our back and freed the handle. In which case just

return an error code.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
