This may cause the PHP process using the driver to terminate unexpectedly, resulting in a loss of availability for that process. The condition occurs below the PHP layer and cannot be intercepted by application-level error handling.\n\n## Affected\n\n- `php_driver >= 1.0.0 < 1.21.12`\n- `php_driver >= 2.1.0 < 2.1.12`\n- `php_driver >= 2.5.0 < 2.5.5`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
