Description OSIDB Bzimport 2025-09-11 17:01:43 UTC

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.
