This occurs because of a lack of proper validation that… | ||
| CVE-2018-12714 | Cri | 0.00 | 9.8 | 0.05 | Jun 24, 2018 | An issue was discovered in the Linux kernel through 4.17.2. The filter parsing in kernel/trace/trace_events_filter.c could be called with no filter, which is an N=0 case when it expected at least one line to have been read, thus making the N-1 index invalid. This allows… | ||
| CVE-2018-12633 | Med | 0.00 | 6.3 | 0.00 | Jun 22, 2018 | An issue was discovered in the Linux kernel through 4.17.2. vbg_misc_device_ioctl() in drivers/virt/vboxguest/vboxguest_linux.c reads the same user data twice with copy_from_user.
