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 2.6.39.2
Description The issue is related to multiple buffer overflows in the Linux kernel, specifically in the net/wireless/nl80211.c file. This can be exploited by local users who have the CAP NET ADMIN capability, allowing them to gain privileges during scan operations when a long SSID value is used.
Recommendations For Linux kernel versions prior to 2.6.39.2, update to version 2.6.39.2 or later to resolve the issue. As a temporary workaround, consider restricting the CAP NET ADMIN capability to minimize the risk of exploitation.
