Detailsinfo

A vulnerability was found in Sonos S1 and S2 (version unknown). It has been classified as critical. Affected is an unknown function in the library mt_7615.ko of the component Wireless Driver. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at sonos.com. This vulnerability is traded as CVE-2023-50809 since 12/14/2023. The exploitability is told to be easy. It is possible to launch the attack remotely. There are known technical details, but no exploit is available.
