Last modified

CVE-2023-50810 is a medium-severity vulnerability rated 6/10 on the CVSS scale. In certain Sonos products before Sonos S1 Release 11.12 and S2 release 15.9, a vulnerability exists in the U-Boot component of the firmware that allow persistent arbitrary code execution with Linux kernel privileges. A failure to correctly handle the return value of the setenv command can be used to override the kernel command-line parameters and ultimately bypass the Secure Boot implementation. EPSS estimates a 0.79% chance of exploitation in the next 30 days.
