"The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE-
SU-2026:21802-1 advisory.

    - Heap Out-of-Bounds Read in Custom Format String Parser via Trailing `%` (bsc#1277205).
    - Path traversal in device-mapper-multipath failed_wwids management (bsc#1277210).
    - SCSI PRIN READ FULL STATUS responses can cause heap buffer overflows (bsc#1277212).
    - Local Denial of Service via Blocking IPC Send Operations (bsc#1277199).
    - Heap Out-of-Bounds Read in GPT Header Validation (bsc#1277209).
    - DoS on multipathd socket by exhausting connections (bsc#1277203).
    - Heap out-of-bounds read in device-mapper-multipath ALUA RTPG parsing (bsc#1277208).

    Changes for multipath-tools:

    - Update to version 0.12.4+278+suse.9cf9c5c.
    - Add missing NULL check in DM parser (gh#opensvc/multipath-tools#155).
