| Vector | AV:L/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions through 6.4.2
Description
An issue in the USB subsystem of the Linux kernel allows for an out-of-bounds read and crash in the
read descriptors function in drivers/usb/core/sysfs.c. This can lead to a denial of service. The issue is related to reading beyond the boundaries of an allocated buffer.Recommendations
For Linux kernel versions through 6.4.2, as a temporary workaround, consider disabling the
read descriptors function in the USB subsystem until a patch is available. Restrict access to the drivers/usb/core/sysfs.c module to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
