Summary: Several security issues were fixed in the Linux kernel.
It was discovered that an out-of-bounds write vulnerability existed in the
Flash-Friendly File System (f2fs) in the Linux kernel. An attacker could
construct a malicious file system that, when mounted, could cause a denial

kernel: NULL pointer dereference due to KEYCTL_READ on negative key
The keyctl_read_key function in security/keys/keyctl.c in the Key Management subcomponent in the Linux kernel before 4.13.5 does not properly consider that a key may be possessed but negatively instantiated, which allows local users to cause a denial of service (OOPS and system crash) via a crafted KEYCTL_READ operation.
A vulnerability was found in the Key Management sub component of the Linux kernel, where when trying to issue a KEYTCL_READ on a negative key would lead to a NULL pointer dereference. A local attacker could use this flaw to crash the kernel.

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.
A flaw was found in the implementation of associative arrays where the add_key systemcall and KEYCTL_UPDATE operations allowed for a NULL payload with a nonzero length. When accessing the payload within this length parameters value, an unprivileged user could trivially cause a NULL pointer dereference (kernel oops).
