CRE-2025-0035 Critical Impact: 7/10 Mitigation: 6/10	psycopg2 SSL error due to thread or forked process state	Applications using psycopg2 with OpenTelemetry instrumentation or threading may fail with SSL-related errors such as "decryption failed or bad record mac". This often occurs when a database connection is created before a fork or from an unsafe thread context, causing the SSL state to become invalid.

CRE-2025-0042 Critical Impact: 7/10 Mitigation: 5/10	PostgreSQL transaction fails with deadlock detected error in psycopg2 and Django	- Applications using Django with PostgreSQL and psycopg2 may encounter `deadlock detected` errors under concurrent write-heavy workloads. - PostgreSQL raises this error when two or more transactions block each other cyclically while waiting for locks, and one must be aborted. - Django surfaces this as an `OperationalError`, and the affected transaction is rolled back.

CRE-2025-0073 High Impact: 9/10 Mitigation: 6/10	Redis Rejects Writes Due to Reaching 'maxmemory' Limit	The Redis instance has reached its configured 'maxmemory' limit. Because its active memory management policy does not permit the eviction of existing keys to free up space (as is the case when the 'noeviction' policy is in effect, which is often the default), Redis rejects new write commands by sending an "OOM command not allowed" error to the client.

CRE-2025-0077 High Impact: 9/10 Mitigation: 7/10	PostgreSQL Fails to Extend File Due to Disk Full	PostgreSQL logs an error when it cannot extend a data file (table/index) because the filesystem is out of disk space. This prevents writes requiring new allocation.	Database Problems	postgresql	PostgreSQL Disk Full Write Failure Public
