CVSS v2.0
5.4
Medium
| Vector | AV:L/AC:M/Au:N/C:P/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 2.6.39
Description
The issue allows local users to obtain potentially sensitive information from kernel stack memory or cause a denial of service, resulting in a system crash. This is due to the
bnep sock ioctl function in net/bluetooth/bnep/sock.c not ensuring that a certain device field ends with a '0' character, which can be exploited via a BNEPCONNADD command.Recommendations
For Linux kernel versions prior to 2.6.39, update to version 2.6.39 or later to resolve the issue. As a temporary workaround, consider restricting access to the
bnep sock ioctl function to minimize the risk of exploitation.Fix
