CVE-2024-42226 in Linux
Summary
by MITRE • 07/30/2024
In the Linux kernel, the following vulnerability has been resolved:
usb: xhci: prevent potential failure in handle_tx_event() for Transfer events without TRB
Some transfer events don't always point to a TRB, and consequently don't have a endpoint ring. In these cases, function handle_tx_event() should not proceed, because if 'ep->skip' is set, the pointer to the endpoint ring is used.
To prevent a potential failure and make the code logical, return after checking the completion code for a Transfer event without TRBs.
If you want to get the best quality for vulnerability data then you always have to consider VulDB.
