A flaw was found in the way the KVM subsystem handled guests attempting to run with the X86_CR4_OSXSAVE CPU feature flag set. On hosts without the XSAVE CPU feature, a local, unprivileged user could use this flaw to crash the host system. A memory disclosure flaw was found in the way the load_script function in the binfmt_script binary format handler handled excessive recursions. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space by executing specially-crafted scripts. A race condition was found in the way the Linux kernel"s ptrace implementation handled PTRACE_SETREGS requests when the debuggee was woken due to a SIGKILL signal instead of being stopped.
