  "details": "In the Linux kernel, the following vulnerability has been resolved:  gfs2: prevent NULL pointer dereference during unmount  When flushing out outstanding glock work during an unmount, gfs2_log_flush() can be called when sdp-\u003esd_jdesc has already been deallocated and sdp-\u003esd_jdesc is NULL.  Commit 35264909e9d1 (\"gfs2: Fix NULL pointer dereference in gfs2_log_flush\") added a check for that to gfs2_log_flush() itself, but it missed the sdp-\u003esd_jdesc dereference in gfs2_log_release().  Fix that.",
