The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:0174 advisory.
- kernel: Use-after-free due to race condition in AF_PACKET implementation (CVE-2018-18559)
- Kernel: speculative bounds check bypass store (CVE-2018-3693)
- kernel: Heap overflow in mwifiex_uap_parse_tail_ies function in drivers/net/wireless/marvell/mwifiex/ie.c (CVE-2019-10126)
- kernel: Count overflow in FUSE request leading to use-after-free issues. (CVE-2019-11487)
- 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: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver (CVE-2019-14816)
- kernel: buffer overflow in cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c (CVE-2019-17133)
- kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure (CVE-2019-18660)
- kernel: Heap overflow in mwifiex_update_bss_desc_with_ie function in marvell/mwifiex/scan.c (CVE-2019-3846)
- kernel: af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr (CVE-2019-8912)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

A Spectre SWAPGS gadget was found in the Linux kernel's implementation of system interrupts. An attacker with local access could use this information to reveal private data through a Spectre like side channel (CVE-2019-1125). A flaw was found in the Linux kernel\u2019s Bluetooth implementation of UART. An attacker with local access and write permissions to the Bluetooth hardware could use this flaw to issue a specially crafted ioctl function call and cause the system to crash (CVE-2019-10207). TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access (CVE-2019-11135). Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access (CVE-2018-12207). For proper mitigations and fixes for theese issues, a microcode update is also needed, either with a bios/uefi update from your hardware vendor or by installing the microcode-0.20191112-1.mga7.nonfree update (mga#25688). There is heap-based buffer overflow in the marvell wifi chip driver that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code (CVE-2019-14814, CVE-2019-14815, CVE-2019-14816). An out-of-bounds access issue was found in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (CVE-2019-14821). A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host (CVE-2019-14835). In the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c allows attackers to obtain sensitive information from kernel stack memory because tos and flags fields are not initialized (CVE-2019-16714) rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow (CVE-2019-17666) For

(CVE-2019-14816)\n\n - A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params() function of Marvell Wifi Driver. (CVE-2019-14815)\n\n - There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. (CVE-2019-14814)\n\n - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)\n\n - A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where, the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.\n (CVE-2019-19338)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope"
