In the Linux kernel, the following vulnerability has been resolved:
net: usb: pegasus: validate USB endpoints
The pegasus 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.
AnalysisAI
The pegasus USB network driver in the Linux kernel fails to validate that connected USB devices have the proper number and types of endpoints before binding to them, allowing a malicious USB device to trigger a kernel crash through null pointer dereference or out-of-bounds memory access. This denial-of-service vulnerability affects Linux kernel versions across multiple stable branches, as evidenced by patches applied to at least six different kernel maintenance branches. …
