The following was filed automatically by setroubleshoot: Summary: Your system may be seriously compromised! Detailed Description: SELinux has denied the vbetool the ability to mmap low area of the kernel address space. The ability to mmap a low area of the address space, as configured by /proc/sys/kernel/mmap_min_addr. Preventing such mappings helps protect against exploiting null deref bugs in the kernel. All applications that need this access should have already had policy written for them. If a compromised application tries modify the kernel this AVC would be generated. This is a serious issue. Your system may very well be compromised. Allowing Access: Contact your security administrator and report this issue.
