In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix potential memory leak in DMUB hwinit [Why] On resume we perform DMUB hwinit which allocates memory: dmresume->dmdmubhwinit->dcdmubsrv_create->kzalloc That results in memory leak in suspend/resume scenarios. [How] Allocate memory for the DC wrapper to DMUB only if it was not allocated before. No need to reallocate it on suspend/resume.
