4Description
In the Linux kernel, the following vulnerability has been resolved: net: usb: kalmia: validate USB endpoints The kalmia driver should validate that the device it is probing has the proper number and types of USB endpoints it is expecting before it binds to it. If a malicious device were to not have the same urbs the driver will crash later on when it blindly accesses these endpoints.
Analysis
The Linux kernel kalmia USB driver fails to validate that connected USB devices have the required endpoints before binding to them, allowing a malicious or malformed USB device to trigger a kernel crash during endpoint access. This denial-of-service vulnerability affects all Linux kernel versions running the kalmia driver (net/usb/kalmia.c) and requires physical USB device connection or local control of USB device enumeration. …
