{"nessus": [{"lastseen": "2023-05-18T14:12:03", "description": "The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-3534 advisory.\n\n - The bpf_int_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 4.0.6 allows local users to cause a denial of service (system crash) by creating a packet filter and then loading crafted BPF instructions that trigger late convergence by the JIT compiler. (CVE-2015-4700)\n\n - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576. (CVE-2016-10088)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic. (CVE-2016-10142)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest. (CVE-2016-9588)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel through 4.3.3 do not verify an address length, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application. (CVE-2015-8569)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request. (CVE-2016-4580)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call. (CVE-2016-9178)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor. (CVE-2016-3140)\n\n - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls. (CVE-2017-6345)\n\n - The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows attackers to cause a denial of service (system crash) via (1) an application that makes crafted system calls or possibly (2) IPv4 traffic with invalid IP options. (CVE-2017-5970)\n\n - Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel 2.6.x through 4.x before 4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request.

multiple vulnerabilities as referenced in the ELSA-2017-3535 advisory.\n\n - The bpf_int_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 4.0.6 allows local users to cause a denial of service (system crash) by creating a packet filter and then loading crafted BPF instructions that trigger late convergence by the JIT compiler. (CVE-2015-4700)\n\n - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576. (CVE-2016-10088)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic. (CVE-2016-10142)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request. (CVE-2016-4580)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.

(CVE-2015-4700)\n\n - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in\n situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary\n kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg\n device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an\n incomplete fix for CVE-2016-9576. (CVE-2016-10088)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious\n application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate\n because it first requires compromising a privileged process and current compiler optimizations restrict\n access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications\n of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the\n generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of\n fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing\n fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed,\n unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to\n DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is\n communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain\n extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between\n Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU\n smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as\n required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received\n ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with\n extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS\n scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they\n implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the\n aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an\n attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message\n with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned\n routers will themselves be the ones dropping their own traffic. (CVE-2016-10142)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause\n a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large\n command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write\n function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain\n privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2\n does not restrict a certain length field, which allows local users to gain privileges or cause a denial of\n service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does\n not properly initialize a certain data structure, which allows attackers to obtain sensitive information\n from kernel stack memory via an X.25 Call Request. (CVE-2016-4580)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations,\n allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not\n properly randomize the legacy base address, which makes it easier for local users to defeat the intended\n restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or\n setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to\n cause a denial of service (system crash) via a crafted application that makes sendto system calls, related\n to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1\n allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system\n crash) via a crafted endpoints value in a USB device descriptor. (CVE-2016-3140)\n\n - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in\n required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have\n unspecified other impact via crafted system calls.

The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576. (CVE-2016-10088)\n\n - The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr call, which allows local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions. (CVE-2016-7097)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - crypto/mcryptd.c in the Linux kernel before 4.8.15 allows local users to cause a denial of service (NULL pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as demonstrated by mcryptd(md5). (CVE-2016-10147)\n\n - arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest. (CVE-2016-9588)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - Double free vulnerability in drivers/net/usb/cdc_ncm.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (system crash) or possibly have unspecified other impact by inserting a USB device with an invalid USB descriptor. (CVE-2016-3951)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS memory consumption) by leveraging the mishandling of page references. (CVE-2017-2596)\n\n - arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in certain error cases, which allows local users to obtain sensitive information from kernel stack memory via a crafted application. (CVE-2016-9756)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability. (CVE-2016-8632)\n\n - The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call. (CVE-2016-9178)\n\n - The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6 mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba.\n (CVE-2015-8952)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor. (CVE-2016-3140)\n\n - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls. (CVE-2017-6345)\n\n - The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows attackers to cause a denial of service (system crash) via (1) an application that makes crafted system calls or possibly (2) IPv4 traffic with invalid IP options. (CVE-2017-5970)\n\n - Race condition in kernel/events/core.c in the Linux kernel before 4.9.7 allows local users to gain privileges via a crafted application that makes concurrent perf_event_open system calls for moving a software group into a hardware context. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-6786. (CVE-2017-6001)\n\n - The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access.

(CVE-2016-7097)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious\n application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate\n because it first requires compromising a privileged process and current compiler optimizations restrict\n access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause\n a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large\n command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write\n function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain\n privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - crypto/mcryptd.c in the Linux kernel before 4.8.15 allows local users to cause a denial of service (NULL\n pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as\n demonstrated by mcryptd(md5). (CVE-2016-10147)\n\n - arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows\n guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by\n an L2 guest. (CVE-2016-9588)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2\n does not restrict a certain length field, which allows local users to gain privileges or cause a denial of\n service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations,\n allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - Double free vulnerability in drivers/net/usb/cdc_ncm.c in the Linux kernel before 4.5 allows physically\n proximate attackers to cause a denial of service (system crash) or possibly have unspecified other impact\n by inserting a USB device with an invalid USB descriptor. (CVE-2016-3951)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not\n properly randomize the legacy base address, which makes it easier for local users to defeat the intended\n restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or\n setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly\n emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS\n memory consumption) by leveraging the mishandling of page references. (CVE-2017-2596)\n\n - arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in\n certain error cases, which allows local users to obtain sensitive information from kernel stack memory via\n a crafted application. (CVE-2016-9756)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to\n cause a denial of service (system crash) via a crafted application that makes sendto system calls, related\n to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the\n relationship between the minimum fragment length and the maximum packet size, which allows local users to\n gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN\n capability. (CVE-2016-8632)\n\n - The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not\n initialize a certain integer variable, which allows local users to obtain sensitive information from\n kernel stack memory by triggering failure of a get_user_ex call. (CVE-2016-9178)\n\n - The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6\n mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via\n filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba.\n (CVE-2015-8952)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1\n allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system\n crash) via a crafted endpoints value in a USB device descriptor. (CVE-2016-3140)\n\n - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in\n required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have\n unspecified other impact via crafted system calls. (CVE-2017-6345)\n\n - The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows\n attackers to cause a denial of service (system crash) via (1) an application that makes crafted system\n calls or possibly (2) IPv4 traffic with invalid IP options. (CVE-2017-5970)\n\n - Race condition in kernel/events/core.c in the Linux kernel before 4.9.7 allows local users to gain\n privileges via a crafted application that makes concurrent perf_event_open system calls for moving a\n software group into a hardware context. NOTE: this vulnerability exists because of an incomplete fix for\n CVE-2016-6786. (CVE-2017-6001)\n\n - The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have\n unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds\n access.

"The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-3567 advisory.\n\n - The __rds_conn_create function in net/rds/connection.c in the Linux kernel through 4.2.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound. (CVE-2015-6937)\n\n - The load_segment_descriptor implementation in arch/x86/kvm/emulate.c in the Linux kernel before 4.9.5 improperly emulates a MOV SS, NULL selector instruction, which allows guest OS users to cause a denial of service (guest OS crash) or gain guest OS privileges via a crafted application. (CVE-2017-2583)\n\n - The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel before 4.9.11 allows remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag. (CVE-2017-6214)\n\n - The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel through 4.10.6 does not validate certain size data after an XFRM_MSG_NEWAE update, which allows local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux- image-* package 4.8.0.41.52. (CVE-2017-7184)\n\n - Race condition in the sctp_wait_for_sndbuf function in net/sctp/socket.c in the Linux kernel before 4.9.11 allows local users to cause a denial of service (assertion failure and panic) via a multithreaded application that peels off an association in a certain buffer-full state. (CVE-2017-5986)\n\n - The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.\n (CVE-2017-7895)\n\n - The vhost_dev_ioctl function in drivers/vhost/vhost.c in the Linux kernel before 4.1.5 allows local users to cause a denial of service (memory consumption) via a VHOST_SET_LOG_FD ioctl call that triggers permanent file-descriptor allocation.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.\n\nSecurity Fix(es) :\n\n* A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system.\n(CVE-2017-2636, Important)\n\n* A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system. (CVE-2017-6074, Important)\n\n* A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. (CVE-2016-8650, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt() system call. Users with non-namespace CAP_NET_ADMIN are able to trigger this call and create a situation in which the sockets sendbuff data size could be negative.\nThis could adversely affect memory allocations and create situations where the system could crash or cause memory corruption.\n(CVE-2016-9793, Moderate)\n\n* A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files.

vulnerabilities :\n\n - arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest.(CVE-2016-9588)\n\n - The IP stack in the Linux kernel before 4.6 allows remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for packets with tunnel stacking, as demonstrated by interleaved IPv4 headers and GRE headers, a related issue to CVE-2016-7039.(CVE-2016-8666)\n\n - The blk_rq_map_user_iov function in block/blk-map.c in the Linux kernel before 4.8.14 does not properly restrict the type of iterator, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device.(CVE-2016-9576)\n\n - Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel before 4.6.3 allows local users to cause a denial of service (double free) or possibly have unspecified other impact via a crafted application that makes sendmsg system calls, leading to a free operation associated with a new dump that started earlier than anticipated.(CVE-2016-9806)\n\n - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c.\n NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576.(CVE-2016-10088)\n\n - A flaw was found in the Linux kernel's implementation of the SCTP protocol.

This could be exploited by guest systems to leak sensitive information or for denial of service (log spam).\n\nCVE-2016-9794\n\nBaozeng Ding reported a race condition in the ALSA (sound) subsystem that could result in a use-after-free. Local users with access to a PCM sound device could exploit this for denial of service (crash or memory corruption) or other security impact.\n\nFor Debian 7 'Wheezy', these problems have been fixed in version 3.2.84-1. This version also includes bug fixes from upstream version 3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.\nFinally, this version adds the option to mitigate security issues in the performance events (perf) subsystem by disabling use by unprivileged users. This can be done by setting sysctl kernel.perf_event_paranoid=3.\n\nFor Debian 8 'Jessie', these problems have been fixed in version 3.16.39-1 which will be included in the next point release (8.6).\n\nWe recommend that you upgrade your linux packages.\n\nNOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory.

This could be exploited by local users with\npermision to access a SCSI device node.\n\nCVE-2015-8963\n\nSasha Levin reported that hot-unplugging a CPU resulted in a\nuse-after-free by the performance events (perf) subsystem, possibly\ncausing a denial of service (crash or memory corruption) or privilege\nescalation. This could by exploited by any local user.\n\nCVE-2015-8964\n\nIt was found that the terminal/serial (tty) subsystem did not reliably\nreset the terminal buffer state when the terminal line discipline was\nchanged. This could allow a local user with access to a terminal\ndevice to read sensitive information from kernel memory.\n\nCVE-2016-7097\n\nJan Kara found that changing the POSIX ACL of a file never cleared its\nset-group-ID flag, which should be done if the user changing it is not\na member of the group-owner. In some cases, this would allow the\nuser-owner of an executable to gain the privileges of the group-owner.\n\nCVE-2016-7910\n\nVegard Nossum discovered that a memory allocation failure while\nhandling a read of /proc/diskstats or /proc/partitions could lead to a\nuse-after-free, possibly causing a denial of service (crash or memory\ncorruption) or privilege escalation.\n\nCVE-2016-7911\n\nDmitry Vyukov reported that a race between ioprio_get() and\nioprio_set() system calls could result in a use-after-free, possibly\ncausing a denial of service (crash) or leaking sensitive information.\n\nCVE-2016-7915\n\nBenjamin Tissoires found that HID devices could trigger an out-of-\nbounds memory access in the HID core. A physically present user could\npossibly use this for denial of service (crash) or to leak sensitive\ninformation.\n\nCVE-2016-8399\n\nQidan He reported that the IPv4 ping socket implementation did not\nvalidate the length of packets to be sent. A user with permisson to\nuse ping sockets could cause an out-of-bounds read, possibly resulting\nin a denial of service or information leak. However, on Debian systems\nno users have permission to create ping sockets by default.\n\nCVE-2016-8633\n\nEyal Itkin reported that the IP-over-Firewire driver (firewire-net)\ndid not validate the offset or length in link-layer fragmentation\nheaders. This allowed a remote system connected by Firewire to write\nto memory after a packet buffer, leading to a denial of service\n(crash) or remote code execution.\n\nCVE-2016-8645\n\nMarco Grassi reported that if a socket filter (BPF program) attached\nto a TCP socket truncates or removes the TCP header, this could cause\na denial of service (crash). This was exploitable by any local user.\n\nCVE-2016-8655\n\nPhilip Pettersson found that the implementation of packet sockets\n(AF_PACKET family) had a race condition between enabling a transmit\nring buffer and changing the version of buffers used, which could\nresult in a use-after-free. A local user with the CAP_NET_ADMIN\ncapability could exploit this for privilege escalation.\n\nCVE-2016-9178\n\nAl Viro found that a failure to read data from user memory might lead\nto a information leak on the x86 architecture (amd64 or i386).\n\nCVE-2016-9555\n\nAndrey Konovalov reported that the SCTP implementation does not\nvalidate 'out of the blue' packet chunk lengths early enough. A remote\nsystem able could use this to cause a denial of service (crash) or\nother security impact for systems using SCTP.\n\nCVE-2016-9576, CVE-2016-10088\n\nDmitry Vyukov reported that using splice() with the SCSI generic\ndriver led to kernel memory corruption. Local users with permision to\naccess a SCSI device node could exploit this for privilege escalation.\n\nCVE-2016-9756\n\nDmitry Vyukov reported that KVM for the x86 architecture (amd64 or\ni386) did not correctly handle the failure of certain instructions\nthat require software emulation on older processors. This could be\nexploited by guest systems to leak sensitive information or for denial\nof service (log spam).\n\nCVE-2016-9794\n\nBaozeng Ding reported a race condition in the ALSA (sound) subsystem\nthat could result in a use-after-free. Local users with access to a\nPCM sound device could exploit this for denial of service (crash or\nmemory corruption) or other security impact.\n\nFor Debian 7 'Wheezy', these problems have been fixed in version\n3.2.84-1. This version also includes bug fixes from upstream version\n3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.\nFinally, this version adds the option to mitigate security issues in\nthe performance events (perf) subsystem by disabling use by\nunprivileged users. This can be done by setting sysctl\nkernel.perf_event_paranoid=3.\n\nFor Debian 8 'Jessie', these problems have been fixed in version\n3.16.39-1 which will be included in the next point release (8.6).\n\nWe recommend that you upgrade your linux packages.\n\nNOTE: Tenable Network Security has extracted the preceding description\nblock directly from the DLA security advisory.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nThese updated kernel packages include several security issues and numerous bug fixes. Space precludes documenting all of these bug fixes in this advisory. To see the complete list of bug fixes, users are directed to the related Knowledge Article:\nhttps://access.redhat.com/articles/2986951.\n\nSecurity Fix(es) :\n\n* A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n* A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042, Moderate)\n\n* It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.\n(CVE-2016-7097, Moderate)\n\n* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399, Moderate)\n\n* It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.\n(CVE-2016-9576, CVE-2016-10088, Moderate)\n\n* A flaw was found in the USB-MIDI Linux kernel driver: a double-free error could be triggered for the 'umidi' object.

4.1.38 to receive various security and bugfixes.\n\nThe following security bugs were fixed :\n\n - CVE-2016-7117: Use-after-free vulnerability in the\n __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077).\n\n - CVE-2017-5551: tmpfs: Fixed a bug that could have allowed users to set setgid bits on files they don't down (bsc#1021258).\n\n - CVE-2016-10147: crypto/mcryptd.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as demonstrated by mcryptd(md5) (bnc#1020381).\n\n - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c.\n NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710).\n\n - CVE-2016-7917: The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel did not check whether a batch message's length field is large enough, which allowed local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability (bnc#1010444).\n\n - CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969).\n\n - CVE-2016-9806: Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel allowed local users to cause a denial of service (double free) or possibly have unspecified other impact via a crafted application that made sendmsg system calls, leading to a free operation associated with a new dump that started earlier than anticipated (bnc#1013540 1017589).\n\n - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531 1013542).\n\nThe following non-security bugs were fixed :\n\n - PCI: generic: Fix pci_remap_iospace() failure path (bsc#1019658).\n\n - bcache: partition support: add 16 minors per bcacheN device (bsc#1019784).\n\n - bnx2x: Correct ringparam estimate when DOWN (bsc#1020214).\n\n - clk: xgene: Do not call __pa on ioremaped address (bsc#1019660).\n\n - kABI workaround for 4.1.37 mount changes (stable-4.1.37).\n\n - kABI: reintroduce sk_filter (bsc#1009969).\n\n - kabi/severities: Ignore inode_change_ok change It's renamed in 4.1.37 to setattr_prepare()\n\n - mpi: Fix NULL ptr dereference in mpi_powm() [ver #3] (bsc#1011820).\n\n - net: introduce __sock_queue_rcv_skb() function (bsc#1009969).\n\n - netback: correct array index (bsc#983348).\n\n - netfront: do not truncate grant references.\n\n - netfront: use correct linear area

This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within\n __sys_recvmmsg() function.(CVE-2016-7117)\n\n - A heap-buffer overflow vulnerability was found in the arcmsr_iop_message_xfer() function in 'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux kernel through 4.8.2. The function does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can potentially cause kernel heap corruption and arbitrary kernel code execution.(CVE-2016-7425)\n\n - A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation.(CVE-2016-7910)\n\n - A use-after-free vulnerability in sys_ioprio_get() was found due to get_task_ioprio() accessing the task-i1/4zio_context without holding the task lock and could potentially race with exit_io_context(), leading to a use-after-free.(CVE-2016-7911)\n\n - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2016-7913)\n\n - The assoc_array_insert_into_terminal_node() function in 'lib/assoc_array.c' in the Linux kernel before 4.5.3 does not check whether a slot is a leaf, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures.(CVE-2016-7914)\n\n - The hid_input_field() function in 'drivers/hid/hid-core.c' in the Linux kernel before 4.6 allows physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device.(CVE-2016-7915)\n\n - Race condition in the environ_read() function in 'fs/proc/base.c' in the Linux kernel before 4.5.4 allows local users to obtain sensitive information from kernel memory by reading a '/proc/*/environ' file during a process-setup time interval in which environment-variable copying is incomplete.(CVE-2016-7916)\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().(CVE-2016-8399)\n\n - Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support is vulnerable to a null pointer dereference flaw. It could occur on x86 platform, when emulating an undefined instruction. An attacker could use this flaw to crash the host kernel resulting in DoS.(CVE-2016-8630)\n\n - A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver firewire-net in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution.The flaw requires firewire-net module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network.(CVE-2016-8633)\n\n - It was discovered that the Linux kernel since 3.6-rc1 with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG() statement in tcp_collapse() function after making a number of certain syscalls leading to a possible system crash.(CVE-2016-8645)\n\n - A vulnerability was found in the Linux kernel. An unprivileged local user could trigger oops in shash_async_export() by attempting to force the in-kernel hashing algorithms into decrypting an empty data set.(CVE-2016-8646)\n\n - A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key.(CVE-2016-8650)\n\n - A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization while creating the TPACKET_V3 ring buffer. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system.(CVE-2016-8655)\n\n - A flaw was found in the way the Linux kernel's networking subsystem handled offloaded packets with multiple layers of encapsulation in the GRO (Generic Receive Offload) code path. A remote attacker could use this flaw to trigger unbounded recursion in the kernel that could lead to stack corruption, resulting in a system crash.(CVE-2016-8666)\n\n - A flaw was discovered in the Linux kernel's implementation of VFIO. An attacker issuing an ioctl can create a situation where memory is corrupted and modify memory outside of the expected area. This may overwrite kernel memory and subvert kernel execution.(CVE-2016-9083)\n\n - The use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached in vfio_pci_intrs.c. This combined with CVE-2016-9083 may allow an attacker to craft an attack and use unallocated memory, potentially crashing the machine.(CVE-2016-9084)\n\n - A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.(CVE-2016-9555)\n\n - It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.(CVE-2016-9576)\n\n - Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled(nested=1), is vulnerable to an uncaught exception issue. It could occur if an L2 guest was to throw an exception which is not handled by an L1 guest.(CVE-2016-9588)\n\n -
