CVEs 3
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: Count overflow in FUSE request leading to use-after-free issues. (CVE-2019-11487)

  • kernel: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel lacks a certain upper-bound check, leading to a buffer overflow (CVE-2019-17666)

  • Kernel: KVM: export MSR_IA32_TSX_CTRL to guest - incomplete fix for TAA (CVE-2019-11135) (CVE-2019-19338)

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):

  • kernel-rt: update to the RHEL7.7.z batch#5 source tree (BZ#1794131)
