[RHSA-2018:3666] kernel-rt security and bug fix update

Severity Moderate
Affected Packages 10
CVEs 2
Info Packages References Vulnerabilities

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

  • kernel: stack-based buffer overflow in chap_server_compute_md5() in iscsi target (CVE-2018-14633)

  • kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service (CVE-2018-14646)

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 Vincent Pelletier for reporting CVE-2018-14633 and Christian Brauner for reporting CVE-2018-14646.

Bug Fix(es):

  • The kernel-rt packages have been upgraded to the 3.10.0-957.1.2 source tree, which provides a number of bug fixes over the previous version. (BZ#1632386)
