From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the qc_info plugin could be confused by a query containing embedded null bytes. Reading information_schema.query_cache_info after such a query was cached could access data beyond the end of a heap-allocated buffer, potentially disclosing adjacent memory or crashing the server. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.\n\n## Affected\n\n- `mariadb >= 10.6.1, < 10.6.28`\n- `mariadb >= 10.11.1, < 10.11.19`\n- `mariadb >= 11.4.1, < 11.4.13`\n- `mariadb >= 11.8.1, < 11.8.9`\n- `mariadb >= 12.3.1, < 12.3.3`\n- `mariadb >= 13.0.1, < 13.0.2`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `mariadb 13.0.2`\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat Hardened Images, Red Hat OpenStack Platform 13 (Queens) · no fix planned: Red Hat OpenStack Platform 13 (Queens), Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, … · updated 2026-10-09 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-107816.json)","depth":"sunlit","depthScore":35,"depthScoreParts":{"impact":35.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
