{"id":"CVE-2026-53102","summary":"wifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req()\n\nmt76_connac_mcu_alloc_sta_req() allocates an skb which is expected to\nbe freed eventually by mt76_mcu_skb_send_msg(). However, currently if\nan intermediate function fails before sending, the allocated skb is\nleaked.\n\nSpecifically, mt76_connac_mcu_sta_wed_update() and\nmt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory\nleak in the error path.\n\nFix this by explicitly freeing the skb in these error paths.\nCommit 7c0f63fe37a5 (\"wifi: mt76: mt7996: fix memory leak on\nmt7996_mcu_sta_key_tlv error\") made a similar change.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review.","modified":"2026-07-08T08:13:45.515971393Z","published":"2026-06-24T16:30:38.536Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53102.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/c41075ce8cf05ed8c0e7b7efef000dce548ffc42"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eb466406d2094deefadc2cd6ddb4f6eeb086d1b4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53102.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53102"},{"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":"6683d988089ce0e80bd859a9493333b6b272420e"},{"fixed":"eb466406d2094deefadc2cd6ddb4f6eeb086d1b4"},{"fixed":"c41075ce8cf05ed8c0e7b7efef000dce548ffc42"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53102.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.18.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53102.json"}}],"schema_version":"1.7.5"}
