CVE-2017-15274: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 4.11.4
