The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ext4: fix string copying in parse_apply_sb_mount_options() strscpy_pad() can't be used to copy a non-NUL-     term string into a NUL-term string of possibly bigger size. Commit 0efc5990bca5 (string.h: Introduce     memtostr() and memtostr_pad()) provides additional information in that regard. So if this happens, the     following warning is observed: strnlen: detected buffer overflow: 65 byte read of buffer size 64 WARNING:

Return with error if the user still     managed to provide a non-NUL-term string here. Found by Linux Verification Center (linuxtesting.org) with     Syzkaller. (CVE-2025-71123)
