Description

In the Linux kernel, the following vulnerability has been resolved:

drm/msm: Add error handling for krealloc in metadata setup

Function msm_ioctl_gem_info_set_metadata() now checks for krealloc failure and returns -ENOMEM, avoiding potential NULL pointer dereference. Explicitly avoids __GFP_NOFAIL due to deadlock risks and allocation constraints.
