CVE-2026-6473 PostgreSQL server undersizes allocations, via integer wraparound

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user...

CVE-2026-6473

CVE-2026-6473 affects PostgreSQL server features where integer wraparound can cause undersized allocations and write out-of-bounds. An unprivileged database user could potentially execute arbitrary code as the OS user running the database, or trigger segmentation faults with gigabyte-scale inputs...

GHSA-97WC-2HQC-CJGR smallbitvec: Integer overflow in safe API leads to heap buffer overflow

Summary An integer overflow in the internal capacity calculation of smallbitvec can lead to an undersized heap allocation, resulting in a heap buffer overflow through safe APIs only. This allows memory corruption without requiring unsafe code from the caller. Details The issue originates from...
