An integer overflow existed in the wolfCrypt CMAC implementation, that could be exploited to forge CMAC tags. The function wcCmacUpdate used the guard if cmac-totalSz != 0 to skip XOR-chaining on the first block where digest is all-zeros and the XOR is a no-op. However, totalSz is word32 and wrap...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to an integer overflow in the wcCmacUpdate function. An attacker can generate forged CMAC tags by exploiting the wraparound of the totalSz variable after processing 4 GiB of data, which causes the...

CVE-2026-5477

The CVE-2026-5477 issue concerns wolfCrypt CMAC: an integer overflow in wc_CmacUpdate caused by a guard that skips XOR-chaining on the first block when cmac->totalSz != 0. totalSz is a 32-bit value and wraps to zero after 2^28 blocks (4 GiB), which can discard the live CBC-MAC chain state. Thi...
