Description of problem: I receive the following selinux alert once a day: Summary: Your system may be seriously compromised! /usr/sbin/wpa_supplicant tried to load a kernel module. Detailed Description: SELinux has prevented wpa_supplicant from loading a kernel module. All confined programs that need to load kernel modules should have already had policy written for them. If a compromised application tries to modify the kernel this AVC will be generated. This is a serious issue. Your system may very well be compromised. Allowing Access: Contact your security administrator and report this issue.
