Summary: An update for kernel is now available for Red Hat Enterprise Linux 7.4 Extended Update Support. 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux ComputeNode EUS (v. 7.4) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.4) - x86_64 Red Hat Enterprise Linux Server EUS (v. 7.4) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 7.4) - noarch, ppc64, ppc64le, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: Use-after-free vulnerability in DCCP socket (CVE-2017-8824, Important) * kernel: v4l2: disabled memory access protection mechanism allowing privilege escalation (CVE-2017-13166, Important) * kernel: Incorrect type conversion for size during dma allocation (CVE-2017-9725, Moderate) * kernel: Use-after-free in snd_seq_ioctl_create_port() (CVE-2017-15265, Moderate) * kernel: Missing namespace check in net/netlink/af_netlink.c allows for network monitors to observe systemwide activity (CVE-2017-17449, Moderate) * kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c (CVE-2017-18017, Moderate) * kernel: kvm: Reachable BUG() on out-of-bounds guest IRQ (CVE-2017-1000252, Moderate) * kernel: Stack information leak in the EFS element (CVE-2017-1000410, Moderate) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank Mohamed Ghannam for reporting CVE-2017-8824; Jan H. SchAPnherr (Amazon) for reporting CVE-2017-1000252; and Armis Labs for reporting CVE-2017-1000410. Bug Fix(es): These updated kernel packages include also numerous bug fixes. Space precludes documenting all of these bug fixes in this advisory. See the bug fix descriptions in the related Knowledge Article: https://access.redhat.com/articles/3411331 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.
