A vulnerability was found in Linux Kernel 2.6.28.2 (Operating System) and classified as problematic. Affected by this issue is the function skfp_ioctl. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is integrity. CVE summarizes:

The skfp_ioctl function in drivers/net/skfp/skfddi.c in the Linux kernel before 2.6.28.6 permits SKFP_CLR_STATS requests only when the CAP_NET_ADMIN capability is absent, instead of when this capability is present, which allows local users to reset the driver statistics, related to an "inverted logic" issue.
