| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition in the Bluetooth subsystem of the Linux kernel can lead to a use-after-free issue. This occurs when an SCO connection is established and the SCO socket is subsequently released; the
timeout work is scheduled to determine if the SCO disconnection has timed out. The socket is deallocated, but it is later dereferenced within the sco sock timeout() function, resulting in the use-after-free. This flaw may allow an attacker to cause a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
