Description OSIDB Bzimport 2025-02-26 03:24:30 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm: msm: fix possible memory leak in mdp5_crtc_cursor_set()

drm_gem_object_lookup will call drm_gem_object_get inside. So cursor_bo
needs to be put when msm_gem_get_and_pin_iova fails.
