Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2016-10905

A race condition was discovered in the GFS2 file-system implementation, which could lead to a use-after-free. On a system using GFS2, a local attacker could use this for denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2018-20976

It was discovered that the XFS file-system implementation did not correctly handle some mount failure conditions, which could lead to a use-after-free. The security impact of this is unclear.

CVE-2018-21008

It was discovered that the rsi wifi driver did not correctly handle some failure conditions, which could lead to a use-after- free. The security impact of this is unclear.

CVE-2019-0136

It was discovered that the wifi soft-MAC implementation (mac80211) did not properly authenticate Tunneled Direct Link Setup (TDLS) messages.
A nearby attacker could use this for denial of service (loss of wifi connectivity).

CVE-2019-9506

Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered a weakness in the Bluetooth pairing protocols, dubbed the 'KNOB attack'. An attacker that is nearby during pairing could use this to weaken the encryption used between the paired devices, and then to eavesdrop on and/or spoof communication between them.

This update mitigates the attack by requiring a minimum encryption key length of 56 bits.

CVE-2019-14814, CVE-2019-14815, CVE-2019-14816

Multiple bugs were discovered in the mwifiex wifi driver, which could lead to heap buffer overflows. A local user permitted to configure a device handled by this driver could probably use this for privilege escalation.

CVE-2019-14821

Matt Delco reported a race condition in KVM's coalesced MMIO facility, which could lead to out-of-bounds access in the kernel. A local attacker permitted to access /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-14835

Peter Pi of Tencent Blade Team discovered a missing bounds check in vhost_net, the network back-end driver for KVM hosts, leading to a buffer overflow when the host begins live migration of a VM. An attacker in control of a VM could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation on the host.

CVE-2019-15117

CVE-2019-15212

The syzkaller tool found that the rio500 driver does not work correctly if more than one device is bound to it. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15215

The syzkaller tool found a bug in the cpia2_usb driver that leads to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15218

The syzkaller tool found that the smsusb driver did not validate that USB devices have the expected endpoints, potentially leading to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15219

The syzkaller tool found that a device initialisation error in the sisusbvga driver could lead to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15220

The syzkaller tool found a race condition in the p54usb driver which could lead to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15221

The syzkaller tool found that the line6 driver did not validate USB devices' maximum packet sizes, which could lead to a heap buffer overrun. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15292

The Hulk Robot tool found missing error checks in the Appletalk protocol implementation, which could lead to a use-after-free. The security impact of this is unclear.

CVE-2019-15807

Jian Luo reported that the Serial Attached SCSI library (libsas) did not correctly handle failure to discover devices beyond a SAS expander. This could lead to a resource leak and crash (BUG). The security impact of this is unclear.

CVE-2019-15917

The syzkaller tool found a race condition in code supporting UART-attached Bluetooth adapters, which could lead to a use- after-free. A local user with access to a pty device or other suitable tty device could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15926

It was found that the ath6kl wifi driver did not consistently validate traffic class numbers in received control packets, leading to out-of-bounds memory accesses. A nearby attacker on the same wifi network could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

For Debian 8 'Jessie', these problems have been fixed in version 3.16.74-1.

Tenable has extracted the preceding description block directly from the Oracle 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.

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0174 advisory.

  - In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add     from setsockopt and bind on an AF_PACKET socket. This issue exists because of the     15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a     certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier     register action. Later, packet_release operates on only one of the two applicable linked lists. The     attacker can achieve Program Counter control. (CVE-2018-18559)

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a speculative buffer overflow and     side-channel analysis. (CVE-2018-3693)

  - A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other     consequences. (CVE-2019-10126)

  - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-     free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - 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)

  - 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)

  - There is heap-based buffer overflow in 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-2019-14816)

  - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a     long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

  - The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is     not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to     arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. (CVE-2019-18660)

  - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the     mwifiex kernel module while connecting to a malicious wireless network. (CVE-2019-3846)

  - In the Linux kernel through 4.20.11, 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.

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The SUSE Linux Enterprise 12-SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.

The Linux Kernel kvm hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port failed to add a port, which may have caused denial of service (bsc#1152685).

CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251 CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150457).

CVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific socket option, an attacker could control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)

CVE-2019-9506: The Bluetooth BR/EDR specification used to permit sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation. This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and inject arbitrary ciphertext without the victim noticing (bnc#1137865).

CVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath was fixed (bnc#1146378).

CVE-2019-15290: A NULL pointer dereference in ath6kl_usb_alloc_urb_from_pipe was fixed (bsc#1146378).

CVE-2019-15239: A incorrect patch to net/ipv4 was fixed. By adding to a write queue between disconnection and re-connection, a local attacker could trigger multiple use-after-free conditions. This could result in kernel crashes or potentially in privilege escalation.
(bnc#1146589)

CVE-2019-15212: A double-free issue was fixed in drivers/usb driver (bnc#1146391).
