Last modified Jun 17, 2026

CVE-2023-50809 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In certain Sonos products before S1 Release 11.12 and S2 release 15.9, the mt_7615.ko wireless driver does not properly validate an information element during negotiation of a WPA2 four-way handshake. This lack of validation leads to a stack buffer overflow. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
