Type/Severity
Security Advisory: Important
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An update for kernel is now available for Red Hat Enterprise Linux 7.2 Advanced Update Support, Red Hat Enterprise Linux 7.2 Telco Extended Update Support, and Red Hat Enterprise Linux 7.2 Update Services for SAP Solutions.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Description
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
- 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)
- kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125)
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.
Bug Fix(es):
- fs deadlock when a memory allocation waits on page writeback in NOFS context (BZ#1729103)
- fragmented packets timing out (BZ#1729409)
- kernel build: speed up debuginfo extraction (BZ#1731460)
- use "make -jN" for modules_install (BZ#1735079)
- shmem: consider shm_mnt as a long-term mount (BZ#1737374)
- raid1d can hang in freeze_array if handling a mix of read and write errors (BZ#1737792)
- Backport TCP follow-up for small buffers (BZ#1739125)
Solution
For details on how to apply this update, which includes the changes described in this advisory, refer to:
