The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003591 advisory.

    drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.2.8 has a NULL pointer dereference via     an incomplete address in an endpoint descriptor.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

The SUSE Linux Enterprise 15 SP1 RT kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-14835: 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 have used this flaw to increase their privileges on the host (bnc#1150112).

CVE-2019-15216: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bnc#1146361).

CVE-2019-15924: fm10k_init_module in drivers/net/ethernet/intel/fm10k/fm10k_main.c had a NULL pointer dereference because there was no -ENOMEM upon an alloc_workqueue failure (bnc#1149612).

CVE-2019-9456: In the Pixel C USB monitor driver there was a possible OOB write due to a missing bounds check. This could have led to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1150025).

CVE-2019-15031: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via an interrupt. To exploit the vulnerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE was misused in arch/powerpc/kernel/process.c (bnc#1149713).

CVE-2019-15030: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check (bnc#1149713).

CVE-2019-15920: SMB2_read in fs/cifs/smb2pdu.c had a use-after-free.
(bnc#1149626).

CVE-2019-15926: An out-of-bounds access existed in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c (bnc#1149527).

CVE-2019-15927: An out-of-bounds access existed in the function build_audio_procunit in the file sound/usb/mixer.c (bnc#1149522).

CVE-2019-15902: Misuse of the upstream 'x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()' commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).

CVE-2019-15666: There was an out-of-bounds array access in
__xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandled directory validation (bnc#1148394).

CVE-2019-15219: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver (bnc#1146524).

CVE-2019-14814: There was a heap-based buffer overflow in the Marvell wifi chip driver, that allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146512).

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1493 advisory.

  - A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before     4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection     negotiation during the handling of the remote devices country settings. This could allow the remote device     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895)

  - A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell     WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a     denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the     availability of the system. If code execution occurs, the code will run with the permissions of root. This     will affect both confidentiality and integrity of files on the system. (CVE-2019-14901)

  - In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of     other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction     (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some     point, the vector registers will be corrupted with the values from a different local Linux process,     because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c. (CVE-2019-15031)

  - drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.2.8 has a NULL pointer dereference via     an incomplete address in an endpoint descriptor. (CVE-2019-15099)

  - An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in
    __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in     net/xfrm/xfrm_user.c mishandles directory validation. (CVE-2019-15666)

  - kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with     Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by     generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words,     although this slice expiration would typically be seen with benign workloads, it is possible that an     attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a     low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray     requests. An attack does not affect the stability of the kernel; it only causes mismanagement of     application execution.) (CVE-2019-19922)

  - In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in     fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. (CVE-2019-20054)

  - mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has     some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will     cause a memory leak and denial of service. (CVE-2019-20095)

  - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An     attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations     before the required authentication process has completed. This could lead to different denial-of-service     scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already     existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge     Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)
