It should not transfer the request when they return\nan error." } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.8, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:L - The vulnerable `tegra_sha_digest()`/`tegra_cmac_digest()` entry points are reached from local userspace via an AF_ALG hash socket (`crypto/algif_hash.c:137` calls `crypto_ahash_digest()`), requiring local system access rather than network reachability. In-kernel consumers such as IPsec `authenc`/AH also reach `.digest`, but the primary and reliable vector is a local syscall sequence.\nAC:L - The only precondition is a `dma_alloc_coherent()` failure, and an unprivileged attacker can create that condition themselves by exhausting and fragmenting memory while looping `send()` on the AF_ALG socket, so both sides of the condition are under attacker control. The attacker also fully controls the algorithm, buffer length and data that get written through the bad pointer.\nPR:L - AF_ALG socket creation and `hash` binding require no capability, so any unprivileged local user or containerized process can invoke the digest path. No CAP_SYS_ADMIN, root, or namespace trick is needed.\nUI:N - The attacker performs the entire sequence — socket/bind/accept/send under self-induced memory pressure — with no action by any other user or administrator.\nS:U - The corruption occurs in kernel memory belonging to the same security authority as the exploiting process; there is no crossing of a VM, hypervisor, or IOMMU boundary. The SE hardware DMA remains behind the SoC's SMMU.\nC:H - The failed-init paths leave `residue.buf`/`datbuf.buf` as dangling-freed or uninitialized stale heap pointers that are subsequently read (`memcpy(rctx->datbuf.buf, rctx->residue.buf, ...)` in `tegra_*_do_final()`) and used as DMA handles for the security engine, and the resulting digest is returned to userspace. This use-after-free/wild-read gives kernel memory disclosure and is leveragable for broader information leak.\nI:H - `tegra_sha_do_update()`/`tegra_cmac_do_update()` write attacker-supplied message bytes of attacker-chosen length through a freed or stale-heap pointer via `scatterwalk_map_and_copy()`, and `tegra_sha_init()`'s `resbuf_fail` path additionally calls `dma_free_coherent()` on an uninitialized pointer. A groomable UAF/wild-write with controlled contents is an arbitrary-write primitive suitable for control-flow hijack.\nA:H - In the common case `datbuf.buf` or `residue.buf` is NULL and the update/final handlers `memcpy()` through it, producing an immediate kernel oops inside the crypto engine kthread; the wild `dma_free_coherent()` and freed-DMA-buffer writes likewise panic the machine. The condition is repeatable at will by an unprivileged user." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/crypto/tegra/tegra-se-aes.c", "drivers/crypto/tegra/tegra-se-hash.c" ], "versions": [ { "version": "0880bb3b00c855fc244b7177ffdaafef4d0aa1e0", "lessThan": "1dbc270f9df7f0ae1e591323431869059cee1b7d", "status": "affected", "versionType": "git" }, { "version": "0880bb3b00c855fc244b7177ffdaafef4d0aa1e0", "lessThan": "5eaa7c916e1ec4b122a1c3a8a20e692d9d9e174e", "status": "affected", "versionType": "git" }, { "version": "0880bb3b00c855fc244b7177ffdaafef4d0aa1e0", "lessThan": "15589bda46830695a3261518bb7627afac61f519", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/crypto/tegra/tegra-se-aes.c", "drivers/crypto/tegra/tegra-se-hash.c" ], "versions": [ { "version": "6.10", "status": "affected" }, { "version": "0", "lessThan": "6.10", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.13", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.13.2", "lessThanOrEqual": "6.13.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.14", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.12.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.13.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.14" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/1dbc270f9df7f0ae1e591323431869059cee1b7d" }, { "url": "https://git.kernel.org/stable/c/5eaa7c916e1ec4b122a1c3a8a20e692d9d9e174e" }, { "url": "https://git.kernel.org/stable/c/15589bda46830695a3261518bb7627afac61f519" } ], "title": "crypto: tegra - do not transfer req when tegra init fails", "x_generator": { "engine": "bippy-1.2.0" } } } }
