Description OSIDB Bzimport 2026-08-15 06:10:11 UTC

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

drm/panthor: Fix potential invalid pointer deref in group_process_tiler_oom()

If heaps is an ERR_PTR(), panthor_heap_pool_put() will deref an invalid
pointer. Make sure we set it to NULL in that case.
