Description OSIDB Bzimport 2026-05-06 10:02:54 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/vc4: Fix memory leak of BO array in hang state

The hang state's BO array is allocated separately with kzalloc() in
vc4_save_hang_state() but never freed in vc4_free_hang_state(). Add the
missing kfree() for the BO array before freeing the hang state struct.
