DEBIAN-CVE-2017-7518

A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flagTF bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exceptionDB being raised in the guest stack. A user/process inside a guest could use this flaw to...

Design/Logic Flaw

The timercreate syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent-sigevnotify field, which leads to out-of-bounds access in the showtimer function called when /proc/$PID/timers is read. This allows userspace applications ...
