Summary
Red Hat Security Advisory: kernel-rt security and bug fix update

Notes

Topic
An update for kernel-rt is now available for Red Hat Enterprise MRG 2. 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.
Details
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: MIDI driver race condition leads to a double-free (CVE-2018-10902) * kernel: net/rxrpc: overflow in decoding of krb5 principal (CVE-2017-7482) * kernel: Missing length check of payload in net/sctp/sm_make_chunk.c:_sctp_make_chunk() function allows denial of service (CVE-2018-5803) * kernel: use-after-free in ntfs_read_locked_inode in the ntfs.ko (CVE-2018-12929) * kernel: stack-based out-of-bounds write in ntfs_end_buffer_async_read in the ntfs.ko (CVE-2018-12930) * kernel: stack-based out-of-bounds write in ntfs_attr_find in the ntfs.ko (CVE-2018-12931) 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): * Remove the NTFS module from the MRG 2.5.x realtime kernel (BZ#1674523) * update the MRG 2.5.z 3.10 kernel-rt sources (BZ#1674935) Users of kernel-rt are advised to upgrade to these updated packages, which fix these bugs.
