CVE-2023-50809

This lack of validation leads to a stack buffer overflow.

HIGH 7.8EPSS 0.39%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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. This can result in remote code execution within the kernel. This affects Amp, Arc, Arc SL, Beam, Beam Gen 2, Beam SL, and Five.
