| CVE-2026-2007 | Hig | 8.2 | < 18.3-1.el10_2 | 18.3-1.el10_2 | Feb 12, 2026 | Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unknown impacts via a crafted input string. The attacker has limited control over the byte patterns to be written, but we have not ruled out the viability of attacks that lead to privilege escalation. | |

That suffices to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL | |
| CVE-2026-2005 | Hig | 8.8 | < 18.3-1.el10_2 | 18.3-1.el10_2 | Feb 12, 2026 | Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. | |
