Description OSIDB Bzimport 2026-08-15 06:35:24 UTC 
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.
