    CVE-2026-15432 (GCVE-0-2026-15432)

    Vulnerability from nvd – Published: 2026-07-21 16:42 – Updated: 2026-07-22 18:27

    Title
    Observable Timing Discrepancy in Tink-Java and Tink-Android ChunkedMacVerification
    Summary
    When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in turn could allow to find a correct tag bytewise.
