7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved:
configfs: fix lockless traversals of ->s_children
Having the parent directory locked protects entries from removal by another thread, but it does not protect cursors from being moved around by lseek() - or freed, for that matter.
