CVE-2023-4265
Potential buffer overflow vulnerabilities in the following locations: https://github.com/zephyrproject-rtos/zephyr/blob/main/drivers/usb/device/usb_dc_native_posix.c#L359…
Does this matter?
Lower severity and a low EPSS score (0.83%). Track it; it rarely justifies an emergency change on its own.
