CVE-2024-50174

CVE-2024-50174 affects the Linux kernel’s panthor DRM path. The issue is a race between retrieving a pointer from an XArray and incrementing its reference count when converting a group handle to a group object. The documented fix is to hold the internal XArray lock while incrementing the referenc...

CVE-2024-50174 drm/panthor: Fix race when converting group handle to group object

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Fix race when converting group handle to group object XArray provides it's own internal lock which protects the internal array when entries are being simultaneously added and removed. However there is still a race...

CVE-2024-50173

The CVE-2024-50173 entry concerns the Linux kernel DRM panthor driver: tick_ctx_cleanup() could access an uninitialized or invalid group-derived ptdev due to using a group variable in the second loop. The fix replaces the approach with obtaining the ptdev object from the scheduler, preventing der...
