CVE-2026-15432

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...

CVE-2026-15432

The CVE concerns Tink-Java and Tink-Android’s ChunkedMacVerification: during tag verification, the implementation uses a non-constant-time comparison, enabling a timing side-channel that could reveal how many bytes of a given tag match the correct tag.
