Detail
Problem Description: An update for kernel-rt is now available for Red Hat Enterprise Linux 8. 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 Real Time (v. 8) - x86_64 Red Hat Enterprise Linux Real Time for NFV (v. 8) - x86_64 3. Description: 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: Heap overflow in mwifiex_update_bss_desc_with_ie function in marvell/mwifiex/scan.c (CVE-2019-3846) * Kernel: KVM: nVMX: guest accesses L0 MSR causes potential DoS (CVE-2019-3887) * kernel: brcmfmac heap buffer overflow in brcmf_wowl_nd_results (CVE-2019-9500) * kernel: Count overflow in FUSE request leading to use-after-free issues. (CVE-2019-11487) * kernel: brcmfmac frame validation bypass (CVE-2019-9503) 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): * BUG: scheduling while atomic in zswap (BZ#1726362) * kernel-rt: update to the RHEL8.0.z batch#3 source tree (BZ#1734475) 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. Bugs fixed (https://bugzilla.redhat.com/): 1695044 - CVE-2019-3887 Kernel: KVM: nVMX: guest accesses L0 MSR causes potential DoS 1701224 - CVE-2019-9500 kernel: brcmfmac heap buffer overflow in brcmf_wowl_nd_results 1701842 - CVE-2019-9503 kernel: brcmfmac frame validation bypass 1703063 - CVE-2019-11487 kernel: Count overflow in FUSE request leading to use-after-free issues. 1713059 - CVE-2019-3846 kernel: Heap overflow in mwifiex_update_bss_desc_with_ie function in marvell/mwifiex/scan.c 1726362 - BUG: scheduling while atomic in zswap [rhel-8.0.0.z] 1734475 - kernel-rt: update to the RHEL8.0.z batch#3 source tree |
