At the same time, an infinite loop problem was fixed in the madvise(2) implementation of the Linux kernel (CVE-2017-18208), a buffer coverage defect in the NCPFS implementation (CVE-2018-8822), and competition in the F2FS implementation. Conditional (CVE-2017-18193), Buffer Overrun in the Hisilicon HNS Ethernet Device Driver (CVE-2017-18222), and Null Pointer Referential Vulnerability in the DCCP Protocol Implementation (CVE-2018-1130).
In the block layer subsystem of the Linux kernel has also solved the double free error (CVE-2018-7480), and SAS subsystem driver memory leaks (CVE-2018-7757) problem, x86 machine check handler The competition conditions (CVE-2018-7995), as well as various other issues in other components, include: Netfilter subsystem, SCTP protocol implementation, netlink subsystem, Xen subsystem, and Bluetooth HIP protocol implementation.
