Vulnerability from github – Published: 2024-08-07 18:30 – Updated: 2025-11-04 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

USB: serial: mos7840: fix crash on resume

Since commit c49cfa917025 ("USB: serial: use generic method if no alternative is provided in usb serial layer"), USB serial core calls the generic resume implementation when the driver has not provided one.

This can trigger a crash on resume with mos7840 since support for multiple read URBs was added back in 2011. Specifically, both port read URBs are now submitted on resume for open ports, but the context pointer of the second URB is left set to the core rather than mos7840 port structure.

Fix this by implementing dedicated suspend and resume functions for mos7840.

Tested with Delock 87414 USB 2.0 to 4x serial adapter.
