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
of service (system crash) or possibly execute arbitrary code.
