The cp_report_fixup function in drivers/hid/hid-cypress.c in the Linux kernel 3.2 and 4.x before 4.9.4 allows physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: Buffer overflow due to unbounded strcpy in ISDN I4L driver (CVE-2017-12762)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - include/linux/init_task.h in the Linux kernel before 2.6.35 does not prevent signals with a process group     ID of zero from reaching the swapper process, which allows local users to cause a denial of service     (system crash) by leveraging access to this process group. (CVE-2010-5328)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.

For more information on this set of information leaks, check out https://www.suse.com/support/kb/doc/?id=7023736

The following security bugs were fixed: CVE-2016-10741:
fs/xfs/xfs_aops.c allowed local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010).

CVE-2017-1000407: By flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021).

CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674).

CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240).

CVE-2017-7472: The KEYS subsystem allowed local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls (bnc#1034862).

CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host.
Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target.
(bnc#1107829).

CVE-2018-15572: The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517 bnc#1105296).

CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946).

CVE-2018-18281: The mremap() syscall performed TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769).

CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825).

CVE-2018-18690: A local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandled ATTR_REPLACE operations with conversion of an attr from short to long form (bnc#1105025).

CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751).

CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841).

CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).

CVE-2018-19985: The function hso_get_config_data in drivers/net/usb/hso.c read if_num from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds (OOB) read that potentially allowed arbitrary read in the kernel address space (bnc#1120743).

CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714).

CVE-2018-5391: The Linux kernel was vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bnc#1103097).

CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a missing bounds check.
This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
(bnc#1108498).

CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bnc#1118319).

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c had multiple race conditions (bnc#1133188). The line discipline was disabled.

CVE-2019-3459: A heap address information leak while using L2CAP_GET_CONF_OPT was discovered (bnc#1120758).

CVE-2019-3460: A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found (bnc#1120758).

CVE-2019-3882: A flaw was found vfio interface implementation that permitted violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS).
(bnc#1131416 bnc#1131427).

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, leading to a use-after-free (bnc#1124728).

CVE-2019-7221: The KVM implementation had a Use-after-Free (bnc#1124732).

CVE-2019-7222: The KVM implementation had an Information Leak (bnc#1124735).

CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166).

CVE-2019-9503: Multiple brcmfmac frame validation bypasses have been fixed (bnc#1132828).

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

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

CVE-2016-2188

Ralf Spenneberg of OpenSource Security reported that the iowarrior device driver did not sufficiently validate USB descriptors. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash).

CVE-2016-9604

It was discovered that the keyring subsystem allowed a process to set a special internal keyring as its session keyring. The security impact in this version of the kernel is unknown.

CVE-2016-10200

Baozeng Ding and Andrey Konovalov reported a race condition in the L2TP implementation which could corrupt its table of bound sockets. A local user could use this to cause a denial of service (crash) or possibly for privilege escalation.

CVE-2017-2647 / CVE-2017-6951

idl3r reported that the keyring subsystem would allow a process to search for 'dead' keys, causing a NULL pointer dereference. A local user could use this to cause a denial of service (crash).

CVE-2017-2671

Daniel Jiang discovered a race condition in the ping socket implementation. A local user with access to ping sockets could use this to cause a denial of service (crash) or possibly for privilege escalation. This feature is not accessible to any users by default.

CVE-2017-5967

Xing Gao reported that the /proc/timer_list file showed information about all processes, not considering PID namespaces. If timer debugging was enabled by a privileged user, this leaked information to processes contained in PID namespaces.

CVE-2017-5970

Andrey Konovalov discovered a denial of service flaw in the IPv4 networking code. This can be triggered by a local or remote attacker if a local UDP or raw socket has the IP_RETOPTS option enabled.

CVE-2017-7184

Chaitin Security Research Lab discovered that the net xfrm subsystem did not sufficiently validate replay state parameters, allowing a heap buffer overflow. This can be used by a local user with the CAP_NET_ADMIN capability for privilege escalation.

CVE-2017-7261

Vladis Dronov and Murray McAllister reported that the vmwgfx driver did not sufficiently validate rendering surface parameters. In a VMware guest, this can be used by a local user to cause a denial of service (crash).

CVE-2017-7273

Benoit Camredon reported that the hid-cypress driver did not sufficiently validate HID reports. This possibly allowed a physically present user with a specially designed USB device to cause a denial of service (crash).

CVE-2017-7294

Li Qiang reported that the vmwgfx driver did not sufficiently validate rendering surface parameters. In a VMware guest, this can be used by a local user to cause a denial of service (crash) or possibly for privilege escalation.

CVE-2017-7308

Andrey Konovalov reported that the packet socket (AF_PACKET) implementation did not sufficiently validate buffer parameters. This can be used by a local user with the CAP_NET_RAW capability for privilege escalation.

CVE-2017-7472

Eric Biggers reported that the keyring subsystem allowed a thread to create new thread keyrings repeatedly, causing a memory leak. This can be used by a local user to cause a denial of service (memory exhaustion).

CVE-2017-7616

Chris Salls reported an information leak in the 32-bit big-endian compatibility implementations of set_mempolicy() and mbind(). This does not affect any architecture supported in Debian 7 LTS.

CVE-2017-7618

Sabrina Dubroca reported that the cryptographic hash subsystem does not correctly handle submission of unaligned data to a device that is already busy, resulting in infinite recursion. On some systems this can be used by local users to cause a denial of service (crash).

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.88-1. This version also includes bug fixes from upstream version 3.2.88, and fixes some older security issues in the keyring, packet socket and cryptographic hash subsystems that do not have CVE IDs.

For Debian 8 'Jessie', most of these problems have been fixed in version 3.16.43-1 which will be part of the next point release.

We recommend that you upgrade your linux packages.
