https://notcve.org/view.php?id=CVE-2017-15274
12 Oct 2017 — security/keys/keyctl.c in the Linux kernel before 4.11.5 does not consider the case of a NULL payload in conjunction with a nonzero length value, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192. security/keys/keyctl.c en el kernel de Linux en versiones anteriores a la 4.11.5 no tiene en cuenta el caso de una carga útil NULL junto con un valor de longitud que no sea cero, lo qu... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5649645d725c73df4302428ee4e02c869248b4c5 • CWE-476: NULL Pointer Dereference •

CVE-2017-1000253 – Linux Kernel PIE Stack Buffer Corruption Vulnerability
https://notcve.org/view.php?id=CVE-2017-1000253
26 Sep 2017 — Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat.
