Description OSIDB Bzimport 2025-12-30 13:15:58 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/msm/a6xx: Replace kcalloc() with kvzalloc()

In order to reduce chance of allocation failure while capturing a6xx
gpu state, use kvzalloc() instead of kcalloc() in state_kcalloc().

Indirectly, this patch helps to fix leaking memory allocated for
gmu_debug object.
