critical Nessus Plugin ID 133480

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0339 advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver (CVE-2019-14816)

* kernel: heap-based buffer overflow in mwifiex_process_country_ie() function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c (CVE-2019-14895)

* kernel: heap overflow in marvell/mwifiex/tdls.c (CVE-2019-14901)

* 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: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi Driver leading to DoS (CVE-2019-14814)

* kernel: heap-overflow in mwifiex_set_wmm_params() function of Marvell WiFi driver leading to DoS (CVE-2019-14815)

* kernel: incomplete fix for race condition between mmget_not_zero()/get_task_mm() and core dumping in CVE-2019-11599 (CVE-2019-14898)

* 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):

* [Azure][8.1] Include patch PCI: hv: Avoid use of hv_pci_dev->pci_slot after freeing it (BZ#1764635)

* block layer: update to v5.3 (BZ#1777766)

* backport xfs: fix missing ILOCK unlock when xfs_setattr_nonsize fails due to EDQUOT (BZ#1778692)

* Backport important bugfixes from upstream post 5.3 (BZ#1778693)

* LUN path recovery issue with Emulex LPe32002 HBA in RHEL 8.0 Server during storage side cable pull testing (BZ#1781108)

* cifs tasks enter D state and error out with CIFS VFS: SMB signature verification returned error = -5 (BZ#1781110)

* Update CIFS to linux 5.3 (except RDMA and conflicts) (BZ#1781113)

* RHEL8.0 - Regression to RHEL7.6 by changing force_latency found during RHEL8.0 validation for SAP HANA on POWER (BZ#1781114)

* blk-mq: overwirte performance drops on real MQ device (BZ#1782181)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL kernel package based on the guidance in RHSA-2020:0339.
