CVE-2023-53548:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2023-53548 affects the Linux kernel's usbnet driver. The vulnerability was discovered by the syzbot fuzzer and involves improper validation of bulk endpoint addresses in the usbnet driver's probe routine (NVD).
Technical details
The vulnerability exists because the usbnet driver trusts the bulk endpoint addresses it receives in the driver_info structure during probe, without verifying that these endpoints actually exist and have the expected type and directions. This leads to a WARNING condition when attempting to submit USB URBs with mismatched pipe types (NVD).
Impact
When exploited, this vulnerability can trigger a warning in the usb_submit_urb function due to mismatched USB pipe types, potentially affecting USB network device functionality (NVD).
Mitigation and workarounds
The fix involves adding proper validation checks for the endpoint types and directions in the usbnet driver's probe routine (NVD).
