https://notcve.org/view.php?id=CVE-2017-1000407
The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic. El kernel de Linux en versiones 2.6.32 y posteriores se ha visto afectado por una denegación de servicio (DoS): al inundar el puerto de diagnóstico 0x80 puede ocurrir una excepción que conduce a una situación de pánico del kernel. Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) is vulnerable to a DoS issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in DoS. • http://www.openwall.com/lists/oss-security/2017/12/04/2 http://www.securityfocus.com/bid/102038 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/security/cve/cve-2017-1000407 https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 https://usn.ubuntu.com/3617-1 https&# • CWE-248: Uncaught Exception CWE-754: Improper Check for Unusual or Exceptional Conditions •
