{"id":"CVE-2026-80937","summary":"wifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy\n\nmt7915_mcu_get_eeprom() copies a fixed EFUSE block into the driver's\ndev-\u003emt76.eeprom.data buffer at the offset reported by the MCU response\n(res-\u003eaddr, a device-controlled __le32) without checking it against the\nbuffer size. A malicious or malfunctioning device can report an arbitrary\naddress and drive a 16-byte out-of-bounds write past eeprom.data.\n\nReject a response whose address would place the copy outside eeprom.data\nbefore deriving the destination pointer. Devices that echo the requested\nin-bounds offset are unaffected.","modified":"2026-09-18T18:26:38.672982937Z","published":"2026-09-11T19:42:10.822Z","related":["openSUSE-SU-2026:11805-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80937.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/44b5adfe49499f53002737f5fe81d608c08122fc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5f48b0d752a76590e2c613aae5345c2474627d1b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5fdaf7016d7684ef756a229fd5d96b4a140eeb40"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80937.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80937"},{"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":"e57b7901469fc0b021930b83a8094baaf3d81b09"},{"fixed":"5fdaf7016d7684ef756a229fd5d96b4a140eeb40"},{"fixed":"5f48b0d752a76590e2c613aae5345c2474627d1b"},{"fixed":"44b5adfe49499f53002737f5fe81d608c08122fc"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-80937.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.8.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-80937.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
