In the Linux kernel, the following vulnerability has been resolved: drm/msm: Add error handling for krealloc in metadata setup Function msmioctlgeminfoset_metadata() now checks for krealloc failure and returns -ENOMEM, avoiding potential NULL pointer dereference. Explicitly avoids _GFPNOFAIL due to deadlock risks and allocation constraints. Patchwork: https://patchwork.freedesktop.org/patch/661235/
