{"id":"CVE-2023-52829","summary":"wifi: ath12k: fix possible out-of-bound write in ath12k_wmi_ext_hal_reg_caps()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: fix possible out-of-bound write in ath12k_wmi_ext_hal_reg_caps()\n\nreg_cap.phy_id is extracted from WMI event and could be an unexpected value\nin case some errors happen. As a result out-of-bound write may occur to\nsoc-\u003ehal_reg_cap. Fix it by validating reg_cap.phy_id before using it.\n\nThis is found during code review.\n\nCompile tested only.","modified":"2026-03-20T12:32:48.640076Z","published":"2024-05-21T15:31:32.164Z","related":["SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52829.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4dd0547e8b45faf6f95373be5436b66cde326c0e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b302dce3d9edea5b93d1902a541684a967f3c63c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dfe13eaab043130f90dd3d57c7d88577c04adc97"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52829.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52829"},{"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":"dfe13eaab043130f90dd3d57c7d88577c04adc97"},{"fixed":"4dd0547e8b45faf6f95373be5436b66cde326c0e"},{"fixed":"b302dce3d9edea5b93d1902a541684a967f3c63c"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52829.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
