However, the ath11k_dp_process_rx()\nfunction access ath11k_soc_dp_stats::hal_reo_error using the REO\ndestination SRNG ring ID, which is incorrect. SRNG ring ID differ from\nnormal ring ID, and this usage leads to out-of-bounds array access. To fix\nthis issue, modify ath11k_dp_process_rx() to use the normal ring ID\ndirectly instead of the SRNG ring ID to avoid out-of-bounds array access.\n\nTested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1" } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:A - The vulnerable code is in the ath11k WiFi receive data path, reached from NAPI processing of REO destination ring descriptors produced by received 802.11 frames. An attacker within radio range of the device injects frames, requiring shared 802.11 medium access but no local presence.\nAC:L - The error branch containing the bad index is entered whenever the REO block flags a frame (duplicate, 2K sequence jump, frame/BAR out-of-range, no BA session, PN check failure), all of which an attacker produces reliably and repeatedly with crafted frames. No unpredictable memory layout or victim state is required.\nPR:N - Frame injection into the hardware receive path requires no account, association, or authentication with the target — REO error classification happens before any credential validation. The attacker needs no privileges on the victim system at all.\nUI:N - The RX path runs unconditionally in NAPI context whenever the interface is up; no victim action such as connecting, opening a file, or loading a module is needed. The attacker simply transmits.\nS:U - The out-of-bounds access corrupts kernel memory adjacent to the ath11k statistics structure, staying within the kernel's own security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The bug performs an out-of-bounds read-modify-write on kernel memory beyond a 4-entry array using an index from an unrelated 0-143 ID namespace, corrupting live driver state in struct ath11k_base. Such memory corruption in a DMA-ring bookkeeping structure can be leveraged toward disclosure of kernel memory.\nI:H - This is an out-of-bounds write — an increment of a u32 past the end of hal_reo_error[], clobbering neighbouring fields including tx_err counters and bp_stats. Per kernel scoring guidance, an out-of-bounds write is High integrity impact.\nA:H - Corrupting driver state beyond the stats array can destabilize the ath11k datapath and produce oops/panic conditions, and the attacker can repeat the triggering frames indefinitely.
