First published: Wed Sep 25 2019(Updated: )

The kernel packages contain the Linux kernel, the core of any Linux operating system.<br>Security Fix(es):<br><li> A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. (CVE-2019-14835)</li> <li> kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125)</li> For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.<br>Bug Fix(es):<br><li> fs deadlock when a memory allocation waits on page writeback in NOFS context (BZ#1729105)</li> <li> fragmented packets timing out (BZ#1729410)</li> <li> kernel build: speed up debuginfo extraction (BZ#1731461)</li> <li> use "make -jN" for modules_install (BZ#1735080)</li> <li> shmem: consider shm_mnt as a long-term mount (BZ#1737375)</li> <li> Backport TCP follow-up for small buffers (BZ#1739126)</li>
