CVSS v2.0
4.7
Média
| Vetor | AV:L/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.12
Description
The issue is related to multiple buffer overflows in the Linux kernel, specifically in the drivers/staging/wlags49 h2/wl priv.c file. This can be exploited by local users with the CAP NET ADMIN capability to cause a denial of service or possibly have other unspecified impacts. The exploitation is related to the
wvlan uil put info and wvlan set station nickname functions when a long station-name string is provided.Recommendations
For Linux kernel versions prior to 3.12, update to version 3.12 or later to resolve the issue. As a temporary workaround, consider restricting the CAP NET ADMIN capability to minimize the risk of exploitation. Additionally, avoid providing long station-name strings to prevent triggering the buffer overflows in the
wvlan uil put info and wvlan set station nickname functions until the issue is resolved.Exploit
