Name of the Vulnerable Software and Affected Versions Linux kernel versions through 6.0.9

Description An issue was discovered in the Linux kernel, where the xillyusb.c file in the drivers/char/xillybus directory has a race condition and use-after-free during physical removal of a USB device. This issue is related to concurrent access to a shared resource with incorrect synchronization, which may allow an attacker to execute arbitrary code.

Recommendations For Linux kernel versions through 6.0.9, consider disabling the xillyusb.c driver or restricting its use until a patch is available. As a temporary workaround, avoid physically removing USB devices while the system is in use to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
