  "description": "In the Linux kernel, the following vulnerability has been resolved:  fuse: abort on fatal signal during sync init  When sync init is used and the server exits for some reason (error, crash) while processing FUSE_INIT, the filesystem creation will hang.  The reason is that while all other threads will exit, the mounting thread (or process) will keep the device fd open, which will prevent an abort from happening.  This is a regression from the async mount case, where the mount was done first, and the FUSE_INIT processing afterwards, in which case there\u0027s no such recursive syscall keeping the fd open.",
