  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\naf_unix: read UNIX_DIAG_VFS data under unix_state_lock\n\nExact UNIX diag lookups hold a reference to the socket, but not to\nu->path. Meanwhile, unix_release_sock() clears u->path under\nunix_state_lock() and drops the path reference after unlocking.\n\nRead the inode and device numbers for UNIX_DIAG_VFS while holding\nunix_state_lock(), then emit the netlink attribute after dropping the\nlock.\n\nThis keeps the VFS data stable while the reply is being built.",
