Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.17.7
Description
The issue exists due to insufficient input validation in the yurex USB driver, specifically in the
yurex read function within the drivers/usb/misc/yurex.c file. This can be exploited by local attackers to crash the kernel or potentially escalate privileges. The vulnerability is related to incorrect bounds checking in the yurex read function, allowing for user access read/writes that could lead to a kernel crash or privilege escalation.Recommendations
For Linux kernel versions prior to 4.17.7, update to version 4.17.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the
yurex USB driver to minimize the risk of exploitation.Correção
