{"id":"CVE-2026-68307","summary":"wifi: mt76: mt7925: fix crash in reset link replay","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7925: fix crash in reset link replay\n\nDuring reset recovery, mt7925_vif_connect_iter() replays firmware state\nfor links tracked in mvif-\u003evalid_links. After MLO link changes or MCU\ntimeout recovery, the driver bitmap can temporarily contain a link whose\nmac80211 bss_conf has already gone away.\n\nThis can pass a NULL bss_conf to mt76_connac_mcu_uni_add_dev(), matching\nthe crash where x1, the second argument, is NULL:\n\npc : mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib]\nlr : mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common]\nx2 : ffffff80a77f6018 x1 : 0000000000000000 x0 : ffffff8099402080\nCall trace:\nmt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib]\nmt7925_vif_connect_iter+0x9c/0x168 [mt7925_common]\nmt7925_mac_reset_work+0x264/0x2f8 [mt7925_common]\n\nSkip missing bss_conf entries before replaying the link. Non-MLO AP/STA\nreset replay is unchanged because the helper still returns &vif-\u003ebss_conf\nfor the legacy link.","modified":"2026-08-18T03:30:53.264359509Z","published":"2026-08-10T12:02:41.904Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68307.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/89d03bda560d635f66d495f37b46a187fd4edfdf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/95b0cf02731c74e073ef8937f5526bd4442a0326"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bd8b2ec838184236c3fcbf738a926328836adf12"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d9326796a378f80be5f9fd60983c62fdccdf2f0b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68307.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68307"},{"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":"14061994184df6bb89cba31657ee1db24480e92a"},{"fixed":"d9326796a378f80be5f9fd60983c62fdccdf2f0b"},{"fixed":"95b0cf02731c74e073ef8937f5526bd4442a0326"},{"fixed":"89d03bda560d635f66d495f37b46a187fd4edfdf"},{"fixed":"bd8b2ec838184236c3fcbf738a926328836adf12"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68307.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.11.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68307.json"}}],"schema_version":"1.9.0"}
