{"id":"CVE-2026-43113","summary":"wifi: wl1251: validate packet IDs before indexing tx_frames","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: wl1251: validate packet IDs before indexing tx_frames\n\nwl1251_tx_packet_cb() uses the firmware completion ID directly to index\nthe fixed 16-entry wl-\u003etx_frames[] array. The ID is a raw u8 from the\ncompletion block, and the callback does not currently verify that it\nfits the array before dereferencing it.\n\nReject completion IDs that fall outside wl-\u003etx_frames[] and keep the\nexisting NULL check in the same guard. This keeps the fix local to the\ntrust boundary and avoids touching the rest of the completion flow.","modified":"2026-07-15T01:48:50.106262383Z","published":"2026-05-06T07:40:39.234Z","related":["CGA-32xf-vx6p-v5qr"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43113.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0fd56fad9c56356e7fa7a7c52e7ecbf807a44eb0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/26ee518695c484f75e3606d631278e84bd24ae02"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6509dbece7339dbc8980c706b9d623119a6de105"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8d7465be5163a923ee5d7459719ef5a021c1584a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a8a11a876f0a97061ee5d9e61d0f5a0df7e241c7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b6ba1eacf276063ebeefbbae8056043c24f2efaf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/df15adc692a802636dd3f258fc7cca8bf7a0ed9a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0dc1ad870d6788b049bfe1511ac75b2333a7550"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43113.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43113"},{"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":"2f01a1f58889fbfeb68b1bc1b52e4197f3333490"},{"fixed":"6509dbece7339dbc8980c706b9d623119a6de105"},{"fixed":"a8a11a876f0a97061ee5d9e61d0f5a0df7e241c7"},{"fixed":"e0dc1ad870d6788b049bfe1511ac75b2333a7550"},{"fixed":"b6ba1eacf276063ebeefbbae8056043c24f2efaf"},{"fixed":"df15adc692a802636dd3f258fc7cca8bf7a0ed9a"},{"fixed":"8d7465be5163a923ee5d7459719ef5a021c1584a"},{"fixed":"26ee518695c484f75e3606d631278e84bd24ae02"},{"fixed":"0fd56fad9c56356e7fa7a7c52e7ecbf807a44eb0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43113.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.31"},{"fixed":"5.10.258"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.136"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.83"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.24"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.14"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43113.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
