Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.16.12

Description The issue is related to errors in handling frame lengths in the Linux kernel, specifically in the drivers/net/usb/sr9700.c file. This can allow an attacker to obtain sensitive information from heap memory by crafting frame lengths from a device.

Recommendations For Linux kernel versions prior to 5.16.12, update to version 5.16.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the sr9700.c driver to minimize the risk of exploitation.
