Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: af_unix: read UNIX_DIAG_VFS data under
unix_state_lock Exact UNIX diag lookups hold a reference to the socket, but not to u->path. Meanwhile,
unix_release_sock() clears u->path under unix_state_lock() and drops the path reference after unlocking.
Read the inode and device numbers for UNIX_DIAG_VFS while holding unix_state_lock(), then emit the netlink
attribute after dropping the lock. This keeps the VFS data stable while the reply is being built.
