Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
fuse: abort on fatal signal during sync init<br />
<br />
When sync init is used and the server exits for some reason (error, crash)<br />
while processing FUSE_INIT, the filesystem creation will hang. The reason<br />
is that while all other threads will exit, the mounting thread (or process)<br />
will keep the device fd open, which will prevent an abort from happening.<br />
<br />
This is a regression from the async mount case, where the mount was done<br />
first, and the FUSE_INIT processing afterwards, in which case there&#39;s no<br />
such recursive syscall keeping the fd open.
