Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/panthor: Fix race when converting group handle to group object<br /> <br /> XArray provides it&amp;#39;s own internal lock which protects the internal array<br /> when entries are being simultaneously added and removed. However there<br /> is still a race between retrieving the pointer from the XArray and<br /> incrementing the reference count.<br /> <br /> To avoid this race simply hold the internal XArray lock when<br /> incrementing the reference count, this ensures there cannot be a racing<br /> call to xa_erase().
