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