the REO exception ring processes frames including those from unknown/invalid peer entries, and in the AP/open-network and rogue-AP scenarios an unauthenticated adjacent attacker can put fragmented frames onto that ring.\nUI:N - The victim only needs its WiFi interface up and operating normally; no click, mount, configuration change, or any other user action is required.\nS:U - The corruption and crash are confined to the kernel's own memory and the ath12k driver's DMA ring state, all within the same security authority \u2014 no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The monitor path performs type-confused reads of a live REO exception ring, interpreting `hal_reo_dest_ring` descriptors and DMA memory as monitor descriptors/cookies, and the clobbered `dst_ring.tp_addr` pointer yields out-of-bounds reads of kernel/MMIO memory that can be leveraged for information disclosure.\nI:H - `ath12k_hal_srng_src_get_next_entry()` run on a DST ring overwrites `u.dst_ring.tp` and the low 32 bits of the `u.dst_ring.tp_addr` pointer, producing a wild write target in `ath12k_hal_srng_access_end()` and desynchronizing an active hardware DMA ring \u2014 memory corruption exploitable for further control over kernel state.\nA:H - `ath12k_dp_mon_buf_replenish()` re-acquires `srng_list[0].lock` already held by `ath12k_dp_mon_rx_process_stats()`, causing a recursive spinlock deadlock in softirq context (CPU hard lockup/panic), in addition to the crashes from the corrupted ring pointers."}]}], "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/hw.c"], "versions": [{"version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "8126f82dab7bd8b2e04799342b19fff0a1fd8575", "status": "affected", "versionType": "git"}, {"version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "36fc66a7d9ca3e5c6eac25362cac63f83df8bed6", "status": "affected", "versionType": "git"}, {"version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "073f9f249eecd64ab9d59c91c4a23cfdcc02afe4", "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/hw.c"], "versions": [{"version": "6.3", "status": "affected"}, {"version": "0", "lessThan": "6.3", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.44", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.10.3", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.11", "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": "6.6.44"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.10.3"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.11"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/8126f82dab7bd8b2e04799342b19fff0a1fd8575"}, {"url": "https://git.kernel.org/stable/c/36fc66a7d9ca3e5c6eac25362cac63f83df8bed6"}, {"url": "https://git.kernel.org/stable/c/073f9f249eecd64ab9d59c91c4a23cfdcc02afe4"}], "title": "wifi: ath12k: fix invalid memory access while processing fragmented packets", "x_generator": {"engine": "bippy-1.2.0"}}, "adp": [{"metrics": [{"other": {"type": "ssvc", "content": {"id": "CVE-2024-43847", "role": "CISA Coordinator", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "version": "2.0.3", "timestamp": "2024-09-10T16:07:36.782917Z"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-12T17:33:21.718Z"}}]}}
