RHSA-2017:2669: Important: kernel-rt security and bug fix update

First published: Wed Sep 06 2017(Updated: )

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.<br>Security Fix(es):<br><li> A race condition was found in the Linux kernel, present since v3.14-rc1 through v4.12. The race happens between threads of inotify_handle_event() and vfs_rename() while running the rename operation against the same file. As a result of the race the next slab data or the slab's free list pointer can be corrupted with attacker-controlled data, which may lead to the privilege escalation. (CVE-2017-7533, Important)</li> <li> It was found that the NFSv4 server in the Linux kernel did not properly validate layout type when processing NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A remote attacker could use this flaw to soft-lockup the system and thus cause denial of service. (CVE-2017-8797, Important)</li> This update also fixes multiple Moderate and Low impact security issues:<br>CVE-2017-8797 CVE-2015-8839 CVE-2016-9576 CVE-2016-7042 CVE-2016-7097 CVE-2016-8645 CVE-2016-9576 CVE-2016-9806 CVE-2016-10088 CVE-2017-2671 CVE-2017-5970 CVE-2017-6001 CVE-2017-6951 CVE-2017-7187 CVE-2017-7889 CVE-2017-8890 CVE-2017-9074 CVE-2017-8890 CVE-2017-9075 CVE-2017-8890 CVE-2017-9076 CVE-2017-8890 CVE-2017-9077 CVE-2016-9604 CVE-2016-9685<br>Documentation for these issues are available from the Technical Notes document linked to in the References section.<br>Red Hat would like to thank Leilei Lin (Alibaba Group), Fan Wu (The University of Hong Kong), and Shixiong Zhao (The University of Hong Kong) for reporting CVE-2017-7533 and Marco Grassi for reporting CVE-2016-8645.
