CVE-2025-37764
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
drm/imagination: fix firmware memory leaks
Free the memory used to hold the results of firmware image processing when the module is unloaded.
Fix the related issue of the same memory being leaked if processing of the firmware image fails during module load.
Ensure all firmware GEM objects are destroyed if firmware image processing fails.
Fixes memory leaks on powervr module unload detected by Kmemleak:
