Vulnerability from cvelistv5

Severity ?
8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix OOB access from firmware ADDBA window size aggr_recv_addba_req_evt() logs a debug message when the firmware-supplied win_sz is outside [AGGR_WIN_SZ_MIN, AGGR_WIN_SZ_MAX] but does not return. The out-of-range win_sz is then used in TID_WINDOW_SZ() to compute a kzalloc size and stored in rxtid->hold_q_sz, leading to zero-size or overflowed allocations and subsequent out-of-bounds access. Clean up any previously active aggregation session for the TID first, then return early when win_sz is out of the valid range, instead of proceeding with a broken allocation size.

The bug is not reachable via user namespaces or unprivileged local syscalls without controlling the WiFi link/firmware messages.\nUI:N - Once the victim device is associated to WiFi (common on phones, embedded, and IoT), the attacker can send ADDBA and follow-up data frames without any additional victim action beyond routine wireless connectivity.\nS:U - Heap corruption and kernel privilege escalation occur within the same kernel security domain; this is not a VM escape, IOMMU bypass, or cross-authority sandbox breakout.\nC:H - Out-of-bounds access to hold_q allows reading/writing adjacent kernel heap memory (e.g., skb pointers and metadata); OOB kernel heap access is treated as arbitrary memory disclosure potential per kernel CVSS guidance.\nI:H - OOB writes to hold_q entries (struct sk_buff pointers, is_amsdu, seq_no) corrupt kernel heap state and can be leveraged for control-flow hijacking and local privilege escalation, not merely a bounded modification.\nA:H - Invalid win_sz can yield zero-size allocations and hold_q_sz=0 (divide-by-zero in AGGR_WIN_IDX) or inconsistent buffers, causing kernel oops/panic or persistent disruption when aggregation receives subsequent frames."

The bug is not reachable via user namespaces or unprivileged local syscalls without controlling the WiFi link/firmware messages.\\nUI:N - Once the victim device is associated to WiFi (common on phones, embedded, and IoT), the attacker can send ADDBA and follow-up data frames without any additional victim action beyond routine wireless connectivity.\\nS:U - Heap corruption and kernel privilege escalation occur within the same kernel security domain; this is not a VM escape, IOMMU bypass, or cross-authority sandbox breakout.\\nC:H - Out-of-bounds access to hold_q allows reading/writing adjacent kernel heap memory (e.g., skb pointers and metadata); OOB kernel heap access is treated as arbitrary memory disclosure potential per kernel CVSS guidance.\\nI:H - OOB writes to hold_q entries (struct sk_buff pointers, is_amsdu, seq_no) corrupt kernel heap state and can be leveraged for control-flow hijacking and local privilege escalation, not merely a bounded modification.\\nA:H - Invalid win_sz can yield zero-size allocations and hold_q_sz=0 (divide-by-zero in AGGR_WIN_IDX) or inconsistent buffers, causing kernel oops/panic or persistent disruption when aggregation receives subsequent frames.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"bdcd81707973cf8aa9305337166f8ee842a050d4\", \"lessThan\": \"c8e3ca7954d8233fbc54bd370c1827670f43c538\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bdcd81707973cf8aa9305337166f8ee842a050d4\", \"lessThan\": \"f480d9910fcfe326db3a6281df80e83af347193e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bdcd81707973cf8aa9305337166f8ee842a050d4\", \"lessThan\": \"67bc9af4f41f2bdba20404fbd753b2a1bd6dd352\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bdcd81707973cf8aa9305337166f8ee842a050d4\", \"lessThan\": \"d4558c140782180e2c80a7588a4af9f8675adfc4\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bdcd81707973cf8aa9305337166f8ee842a050d4\", \"lessThan\": \"5a65fd4722416061698b0a3277222381efbc4882\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bdcd81707973cf8aa9305337166f8ee842a050d4\", \"lessThan\": \"58c6c8dc2e022e1b4f3dc58725a1ca49ff470f9c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bdcd81707973cf8aa9305337166f8ee842a050d4\", \"lessThan\": \"cec0a487cf38ac1f9bca240ffe8a94c5014b72f2\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bdcd81707973cf8aa9305337166f8ee842a050d4\", \"lessThan\": \"44126b6994eeb28f2103b638e698f40a1244f327\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/net/wireless/ath/ath6kl/txrx.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3.2\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"3.2\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.265\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.216\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.183\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.148\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.101\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.42\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.6\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/net/wireless/ath/ath6kl/txrx.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/c8e3ca7954d8233fbc54bd370c1827670f43c538\"}, {\"url\": \"https://git.kernel.org/stable/c/f480d9910fcfe326db3a6281df80e83af347193e\"}, {\"url\": \"https://git.kernel.org/stable/c/67bc9af4f41f2bdba20404fbd753b2a1bd6dd352\"}, {\"url\": \"https://git.kernel.org/stable/c/d4558c140782180e2c80a7588a4af9f8675adfc4\"}, {\"url\": \"https://git.kernel.org/stable/c/5a65fd4722416061698b0a3277222381efbc4882\"}, {\"url\": \"https://git.kernel.org/stable/c/58c6c8dc2e022e1b4f3dc58725a1ca49ff470f9c\"}, {\"url\": \"https://git.kernel.org/stable/c/cec0a487cf38ac1f9bca240ffe8a94c5014b72f2\"}, {\"url\": \"https://git.kernel.org/stable/c/44126b6994eeb28f2103b638e698f40a1244f327\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nwifi: ath6kl: fix OOB access from firmware ADDBA window size\\n\\naggr_recv_addba_req_evt() logs a debug message when the firmware-supplied\\nwin_sz is outside [AGGR_WIN_SZ_MIN, AGGR_WIN_SZ_MAX] but does not\\nreturn.
