no remote peer data path (IPsec AH needs shash-based hmac) reaches it.\nAC:L - The use-after-free is unconditional in code order — the driver always touches the request after signalling completion — and the attacker fully controls when the request is freed/reused (closing the AF_ALG socket or the caller's own callback), so the window is attacker-created and repeatable.\nPR:L - Any unprivileged local user can drive the rk3288 hash engine via an AF_ALG socket or by reading dm-verity/fs-verity backed files; no capability, root, or namespace privilege is checked along the path.\nUI:N - Exploitation only requires the attacker's own hashing requests; no action by another user or administrator is needed.\nS:U - The corruption stays within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed by the bug itself.\nC:H - The freed request is re-read after being handed back to the caller, and the attacker can groom the reallocated slab contents, so the stale `rctx->dev`/`areq->src`/`nrsg` values yield a kernel-memory read primitive usable for information disclosure.\nI:H - Use-after-free with attacker-controlled reallocated contents drives `dma_unmap_sg()` on a forged device pointer and forged scatterlist, allowing DMA/IOVA teardown and heap-spray-based control-flow corruption — an arbitrary-write-grade primitive.\nA:H - Even unexploited, dereferencing the freed request and unmapping a bogus scatterlist reliably oopses or panics the kernel, and the condition can be triggered repeatedly 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/rockchip/rk3288_crypto_ahash.c" ], "versions": [ { "version": "c66c17a0f69b0e017bbc01d999a28ed96ee84826", "lessThan": "48dd260fdb728eda4a246f635d1325e82f0d3555", "status": "affected", "versionType": "git" }, { "version": "c66c17a0f69b0e017bbc01d999a28ed96ee84826", "lessThan": "eb2a41a8ae8c8c4f68aef3bd94665c0cf23e04be", "status": "affected", "versionType": "git" }, { "version": "c66c17a0f69b0e017bbc01d999a28ed96ee84826", "lessThan": "c0afb6b88fbbc177fa322a835f874be217bffe45", "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/rockchip/rk3288_crypto_ahash.c" ], "versions": [ { "version": "6.6", "status": "affected" }, { "version": "0", "lessThan": "6.6", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.24", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7.12", "lessThanOrEqual": "6.7.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8", "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": "6.6", "versionEndExcluding": "6.6.24" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.7.12" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.8" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/48dd260fdb728eda4a246f635d1325e82f0d3555" }, { "url": "https://git.kernel.org/stable/c/eb2a41a8ae8c8c4f68aef3bd94665c0cf23e04be" }, { "url": "https://git.kernel.org/stable/c/c0afb6b88fbbc177fa322a835f874be217bffe45" } ], "title": "crypto: rk3288 - Fix use after free in unprepare", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CISA ADP Vulnrichment", "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-35792", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-05-28T15:22:56.349397Z" } } } ], "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-04T17:33:41.714Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T03:21:47.351Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/48dd260fdb728eda4a246f635d1325e82f0d3555", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/eb2a41a8ae8c8c4f68aef3bd94665c0cf23e04be", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/c0afb6b88fbbc177fa322a835f874be217bffe45", "tags": [ "x_transferred" ] } ] } ] } }
