this matches the ath12k host-firmware trust-boundary scoring used for CVE-2023-52829.\nAC:L - Firmware fully controls the 16-bit payload_size in the HTT header; once an oversized len is supplied the TLV walk past skb->len is deterministic with no race or uncontrollable memory-layout requirement.\nPR:N - The HTT T2H handler runs automatically on device-delivered messages during normal radio operation with no OS credential, capability, or authentication check on the path, as with other ath12k firmware CE/HTC parsers.\nUI:N - PPDU stats indications are requested at mac start and processed in the driver’s RX completion path without any local user action such as opening a file or changing configuration.\nS:U - The out-of-bounds read and any resulting crash or corrupted driver stats remain inside the host kernel/driver security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - An unbounded out-of-bounds read (claimed len up to 65535 versus ~2KB CE skb) walks adjacent kernel memory and copies TLV payloads into ppdu_info; per guidance OOB reads are Confidentiality High.\nI:N - The live defect is an out-of-bounds read; memcpy destinations in ath12k_htt_tlv_ppdu_stats_parse are fixed-size in-bounds fields, and the num_users OOB-write loops are unreachable because frame_type/tlv_bitmap are never set.\nA:H - Walking tens of kilobytes past the skb into potentially unmapped kernel memory can trigger a kernel oops/panic, which is Availability High." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/ath/ath12k/dp_rx.c" ], "versions": [ { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "79527c21a3ce04cffc35ea54f74ee087e532be57", "status": "affected", "versionType": "git" }, { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "c9e44111da221246efb2e623ae1be40a5cf6542c", "status": "affected", "versionType": "git" }, { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "1bc44a505a229bb1dd4957e11aa594edeea3690e", "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/net/wireless/ath/ath12k/dp_rx.c" ], "versions": [ { "version": "6.3", "status": "affected" }, { "version": "0", "lessThan": "6.3", "status": "unaffected", "versionType": "semver" }, { "version": "6.5.13", "lessThanOrEqual": "6.5.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.3", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7", "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": "6.3", "versionEndExcluding": "6.5.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.6.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.7" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/79527c21a3ce04cffc35ea54f74ee087e532be57" }, { "url": "https://git.kernel.org/stable/c/c9e44111da221246efb2e623ae1be40a5cf6542c" }, { "url": "https://git.kernel.org/stable/c/1bc44a505a229bb1dd4957e11aa594edeea3690e" } ], "title": "wifi: ath12k: fix possible out-of-bound read in ath12k_htt_pull_ppdu_stats()", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CISA ADP Vulnrichment", "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2023-52827", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-05-22T18:23:07.677346Z" } } } ], "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-04T17:22:45.297Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T23:11:36.061Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/79527c21a3ce04cffc35ea54f74ee087e532be57", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/c9e44111da221246efb2e623ae1be40a5cf6542c", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/1bc44a505a229bb1dd4957e11aa594edeea3690e", "tags": [ "x_transferred" ] } ] } ] } }
