{"id":"CVE-2025-38199","summary":"wifi: ath12k: Fix memory leak due to multiple rx_stats allocation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: Fix memory leak due to multiple rx_stats allocation\n\nrx_stats for each arsta is allocated when adding a station.\narsta-\u003erx_stats will be freed when a station is removed.\n\nRedundant allocations are occurring when the same station is added\nmultiple times. This causes ath12k_mac_station_add() to be called\nmultiple times, and rx_stats is allocated each time. As a result there\nis memory leaks.\n\nPrevent multiple allocations of rx_stats when ath12k_mac_station_add()\nis called repeatedly by checking if rx_stats is already allocated\nbefore allocating again. Allocate arsta-\u003erx_stats if arsta-\u003erx_stats\nis NULL respectively.\n\nTested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1\nTested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3","modified":"2026-04-02T12:47:51.578425Z","published":"2025-07-04T13:37:21.227Z","related":["CGA-6xjm-p3mg-w4fg"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38199.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/232f962ae5fca98912a719e64b4964a5aec7c99b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c426497fa2055c8005196922e7d29c41d7e0948a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38199.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38199"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d889913205cf7ebda905b1e62c5867ed4e39f6c2"},{"fixed":"232f962ae5fca98912a719e64b4964a5aec7c99b"},{"fixed":"c426497fa2055c8005196922e7d29c41d7e0948a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-38199.json"}}],"schema_version":"1.7.5"}
