    CVE-2026-12087 (GCVE-0-2026-12087)

    Vulnerability from nvd – Published: 2026-06-15 21:11 – Updated: 2026-06-16 15:59

    Title
    Socket versions before 2.041 for Perl have an out-of-bounds heap read
    Summary
    Socket versions before 2.041 for Perl have an out-of-bounds heap read. In Socket.xs, pack_ip_mreq_source() checks the length of its source argument before the argument is read, so the check tests the byte length carried over from the preceding multiaddr argument instead. Both addresses occupy a 4-byte field, so a valid multiaddr lets a source of any length pass the check, and the source is then copied into the 4-byte imr_sourceaddr field with a fixed-size copy. A source shorter than 4 bytes is not rejected, and the copy reads up to 3 bytes past the end of its buffer. Calling pack_ip_mreq_source() with a source value shorter than 4 bytes copies adjacent heap memory into the returned packed structure.
