{"id":"CVE-2026-31779","summary":"wifi: iwlwifi: mvm: fix potential out-of-bounds read in iwl_mvm_nd_match_info_handler()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: mvm: fix potential out-of-bounds read in iwl_mvm_nd_match_info_handler()\n\nThe memcpy function assumes the dynamic array notif-\u003ematches is at least\nas large as the number of bytes to copy. Otherwise, results-\u003ematches may\ncontain unwanted data. To guarantee safety, extend the validation in one\nof the checks to ensure sufficient packet length.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.","modified":"2026-06-18T03:57:06.521230222Z","published":"2026-05-01T14:15:06.506Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31779.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/744fabc338e87b95c4d1ff7c95bc8c0f834c6d99"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca0e9491b98ca4c5b44204b0b3dd8062a3b5fba2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dd90880eb5ec5442b37eb2b95688f4a63f4883e3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e67d8c626ace80b0fa2b48c8ec0a46b508c93442"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6abac936a0dfd31d6c3e49205ec0ee75a8f887f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ffbed27ba15ef80d1c622eeedbfef03e501ae134"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31779.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31779"},{"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":"5ac54afd4d97ad8d94fe250c83b1924eb6d2268c"},{"fixed":"f6abac936a0dfd31d6c3e49205ec0ee75a8f887f"},{"fixed":"ffbed27ba15ef80d1c622eeedbfef03e501ae134"},{"fixed":"e67d8c626ace80b0fa2b48c8ec0a46b508c93442"},{"fixed":"dd90880eb5ec5442b37eb2b95688f4a63f4883e3"},{"fixed":"ca0e9491b98ca4c5b44204b0b3dd8062a3b5fba2"},{"fixed":"744fabc338e87b95c4d1ff7c95bc8c0f834c6d99"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-31779.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.168"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.134"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.81"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.22"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-31779.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:N/A:H"}]}
