  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ngfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump\n\nSyzkaller has reported a NULL pointer dereference when accessing\nrgd->rd_rgl in gfs2_rgrp_dump().  This can happen when creating\nrgd->rd_gl fails in read_rindex_entry().  Add a NULL pointer check in\ngfs2_rgrp_dump() to prevent that.",
