Public on 2026-10-16
Modified on 2026-10-19
Description
A flaw was found in MariaDB. An authenticated database user can exploit an out-of-bounds read vulnerability by supplying a specially crafted spatial geometry to the ST_Area function. This issue allows reading beyond allocated memory buffers, leading to unauthorized information disclosure of internal process memory. An attacker could use this disclosed data to facilitate further attacks, such as bypassing security protections like Address Space Layout Randomization (ASLR).
