Prior to 5.5.0, run_maintenance() handles exceptions outside the loop that processes rows from part_config, so an exception for one partition set immediately terminates the loop and skips every later set. A role with partman_user access can insert or update a row that reliably fails and assign it a low maintenance_order value so it is processed before legitimate rows. Repeated maintenance ticks then abort before legitimate partition sets are maintained, causing database-wide loss of automated partition maintenance. This issue is fixed in version 5.5.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-24 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-61822.json)","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
