  "title": "crypto: qce - fix CCM AAD buffer underallocation",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  crypto: qce - fix CCM AAD buffer underallocation  The AAD buffer allocated in qce_aead_ccm_prepare_buf_assoclen() can be smaller than the length later programmed into the DMA scatterlist.  The allocation size is currently calculated as:    ALIGN(assoclen, 16) \u002B MAX_CCM_ADATA_HEADER_LEN  while the DMA length is set to:    ALIGN(assoclen \u002B adata_header_len, 16)  Since ALIGN() does not distribute over addition, the allocation can be smaller than the DMA length. For example, when assoclen = 32 and adata_header_len = 2:    allocation = ALIGN(32, 16) \u002B 6 = 38   DMA length = ALIGN(32 \u002B 2, 16) = 48  As a result, the QCE hardware can read beyond the allocated buffer while computing the CBC-MAC over the associated data. The extra bytes are folded into the authentication tag, resulting in an incorrect tag and causing CCM self-test failures such as:    alg: aead: ccm-aes-qce encryption test failed (wrong result)   on test vector 8  Fix the allocation by adding the maximum possible AAD header length before alignment:    ALIGN(assoclen \u002B MAX_CCM_ADATA_HEADER_LEN, 16)  This guarantees that the allocated buffer is large enough for the fully padded AAD data for all supported header sizes.",
