    Altan Birler discovered that PostgreSQL incorrectly validated oidvector types. An attacker could possibly
    use this issue to obtain a few bytes of sensitive information. (CVE-2026-2003)

    Daniel Firer discovered that PostgreSQL incorrectly validated input in the intarray extension. An attacker
    could possibly use this issue to execute arbitrary code. (CVE-2026-2004)

    It was dicovered that PosgreSQL incorrectly handled certain pgcrypto memory operations. An attacker could
    possibly use this issue to execute arbitrary code. (CVE-2026-2005)

    Paul Gerste and Moritz Sanft discovered that PostgreSQL incorrectly validated multibyte character lengths.
    An attacker could possibly use this issue to execute arbitrary code. (CVE-2026-2006)
