CVE-2026-107821
Description
A flaw was found in MariaDB. An attacker able to place a crafted table format (FRM) metadata file into the database data directory can exploit insufficient validation of metadata boundaries and field counts when the server opens the file. This could lead to out-of-bounds memory operations, potentially allowing arbitrary code execution or causing a Denial of Service (DoS) by crashing the database server.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
