Title
crypto: s390/aes - Fix buffer overread in CTR mode
Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: s390/aes - Fix buffer overread in CTR mode When processing the last block, the s390 ctr code will always read a whole block, even if there isn't a whole block of data left. Fix this by using the actual length left and copy it into a buffer first for processing.

on an IPsec gateway, attacker-controlled forwarded packet lengths hit authenc encrypt which calls crypto_skcipher_encrypt before ICV generation, so the vulnerable CTR path processes remote traffic.\\nAC:L - The attacker reliably triggers the partial final-block path by choosing a cryptlen that is not a multiple of AES_BLOCK_SIZE, and can place that remainder near a page boundary via packet or AF_ALG buffer sizing with no uncontrollable race.\\nPR:N - Outbound ESP encryption on a configured IPsec/XFRM path runs on forwarded packets without a local account or capability; SA/policy setup is deployment configuration, not attacker privilege.\\nUI:N - No victim interaction is required; crafted packet lengths or local AF_ALG send/recv sequences alone exercise the vulnerable final-block read.\\nS:U - Impact stays inside the same kernel authority (crypto/XFRM on the host) and does not demonstrate VM escape, IOMMU bypass, or another cross-scope boundary.\\nC:L - The bug over-reads up to 15 bytes of adjacent source memory into the KMCTR path; that is a strictly bounded OOB read (not arbitrary), and the truncated memcpy to dst does not return those bytes, so confidentiality is limited rather than high.\\nI:N - This is a source overread only\\u2014destination writes are already limited to nbytes\\u2014and CTR output for the valid bytes is not an integrity-corrupting write primitive.\\nA:H - Reading a full AES block when nbytes is smaller can touch the next page beyond the scatterwalk mapping (or a guard/KFENCE page), causing a kernel fault/oops and denial of service.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"0200f3ecc19660bebeabbcbaf212957fcf1dbf8f\", \"lessThan\": \"cd51e26a3b89706beec64f2d8296cfb1c34e0c79\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0200f3ecc19660bebeabbcbaf212957fcf1dbf8f\", \"lessThan\": \"a7f580cdb42ec3d53bbb7c4e4335a98423703285\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0200f3ecc19660bebeabbcbaf212957fcf1dbf8f\", \"lessThan\": \"dbc9a791a70ea47be9f2acf251700fe254a2ab23\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0200f3ecc19660bebeabbcbaf212957fcf1dbf8f\", \"lessThan\": \"d68ac38895e84446848b7647ab9458d54cacba3e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0200f3ecc19660bebeabbcbaf212957fcf1dbf8f\", \"lessThan\": \"e78f1a43e72daf77705ad5b9946de66fc708b874\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0200f3ecc19660bebeabbcbaf212957fcf1dbf8f\", \"lessThan\": \"d07f951903fa9922c375b8ab1ce81b18a0034e3b\", \"versionType\": \"git\"}], \"programFiles\": [\"arch/s390/crypto/aes_s390.c\", \"arch/s390/crypto/paes_s390.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3.0\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"3.0\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.210\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.149\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.76\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.15\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7.3\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.7.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"arch/s390/crypto/aes_s390.c\", \"arch/s390/crypto/paes_s390.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/cd51e26a3b89706beec64f2d8296cfb1c34e0c79\"}, {\"url\": \"https://git.kernel.org/stable/c/a7f580cdb42ec3d53bbb7c4e4335a98423703285\"}, {\"url\": \"https://git.kernel.org/stable/c/dbc9a791a70ea47be9f2acf251700fe254a2ab23\"}, {\"url\": \"https://git.kernel.org/stable/c/d68ac38895e84446848b7647ab9458d54cacba3e\"}, {\"url\": \"https://git.kernel.org/stable/c/e78f1a43e72daf77705ad5b9946de66fc708b874\"}, {\"url\": \"https://git.kernel.org/stable/c/d07f951903fa9922c375b8ab1ce81b18a0034e3b\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ncrypto: s390/aes - Fix buffer overread in CTR mode\\n\\nWhen processing the last block, the s390 ctr code will always read\\na whole block, even if there isn\u0027t a whole block of data left.
