VetorAV:L/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.2.9
Description The issue is related to a use-after-free bug in the Linux kernel, specifically in the drivers/usb/misc/yurex.c driver. This bug can be triggered by a malicious USB device, potentially allowing an attacker to cause a denial of service or elevate their privileges.
Recommendations For Linux kernel versions prior to 5.2.9, update to version 5.2.9 or later to resolve the issue. As a temporary workaround, consider disabling the use of the drivers/usb/misc/yurex.c driver until a patch is available. Restrict access to USB devices to minimize the risk of exploitation.
