CVE-2016-0728 6 Canonical, Debian, Google and 3 more 9 Ubuntu Linux, Debian Linux, Android and 6 more 2024-08-05 7.8 High
The join_session_keyring function in security/keys/process_keys.c in the Linux kernel before 4.4.1 mishandles object references in a certain error case, which allows local users to gain privileges or cause a denial of service (integer overflow and use-after-free) via crafted keyctl commands.
CVE-2017-1000410 3 Debian, Linux, Redhat 13 Debian Linux, Linux Kernel, Enterprise Linux and 10 more 2024-08-05 N/A
The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. These are the specifics of this vulnerability: In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs, (void *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(&ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes).
CVE-2017-1000364 2 Linux, Redhat 10 Linux Kernel, Container Development Kit, Enterprise Linux and 7 more 2024-08-05 N/A
An issue was discovered in the size of the stack guard page on Linux, specifically a 4k stack guard page is not sufficiently large and can be "jumped" over (the stack guard page is bypassed), this affects Linux Kernel versions 4.11.5 and earlier (the stackguard page was introduced in 2010).
CVE-2017-1000379 2 Linux, Redhat 9 Linux Kernel, Enterprise Linux, Enterprise Mrg and 6 more 2024-08-05 7.8 High
The Linux Kernel running on AMD64 systems will sometimes map the contents of PIE executable, the heap or ld.so to where the stack is mapped allowing attackers to more easily manipulate the stack. Linux Kernel version 4.11.5 is affected.
CVE-2017-1000251 4 Debian, Linux, Nvidia and 1 more 17 Debian Linux, Linux Kernel, Jetson Tk1 and 14 more 2024-08-05 8.0 High
The native Bluetooth stack in the Linux Kernel (BlueZ), starting at the Linux kernel version 2.6.32 and up to and including 4.13.1, are vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space.
CVE-2017-1000380 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more 2024-08-05 N/A
sound/core/timer.c in the Linux kernel before 4.11.5 is vulnerable to a data race in the ALSA /dev/snd/timer driver resulting in local users being able to read information belonging to other users, i.e., uninitialized memory contents may be disclosed when a read and an ioctl happen at the same time.
CVE-2017-1000111 3 Debian, Linux, Redhat 11 Debian Linux, Linux Kernel, Enterprise Linux and 8 more 2024-08-05 7.8 High
Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW.
CVE-2017-1000112 2 Linux, Redhat 8 Linux Kernel, Enterprise Linux, Enterprise Mrg and 5 more 2024-08-05 7.0 High
Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption. In case UFO packet lengths exceeds MTU, copy = maxfraglen - skb->len becomes negative on the non-UFO path and the branch to allocate new skb is taken. This triggers fragmentation and computation of fraggap = skb_prev->len - maxfraglen. Fraggap can exceed MTU, causing copy = datalen - transhdrlen - fraggap to become negative. Subsequently skb_copy_and_csum_bits() writes out-of-bounds. A similar issue is present in IPv6 code. The bug was introduced in e89e9cf539a2 ("[IPv4/IPv6]: UFO Scatter-gather approach") on Oct 18 2005.
CVE-2017-18595 3 Linux, Opensuse, Redhat 9 Linux Kernel, Leap, Enterprise Linux and 6 more 2024-08-05 7.8 High
An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c.
CVE-2017-18344 3 Canonical, Linux, Redhat 16 Ubuntu Linux, Linux Kernel, Enterprise Linux and 13 more 2024-08-05 N/A
The timer_create syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent->sigev_notify field, which leads to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allows userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE).
CVE-2017-18208 2 Linux, Redhat 8 Linux Kernel, Enterprise Linux, Enterprise Mrg and 5 more 2024-08-05 N/A
The madvise_willneed function in mm/madvise.c in the Linux kernel before 4.14.4 allows local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping.
CVE-2017-18017 9 Arista, Canonical, Debian and 6 more 33 Eos, Ubuntu Linux, Debian Linux and 30 more 2024-08-05 9.8 Critical
The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.
CVE-2017-17558 3 Linux, Redhat, Suse 6 Linux Kernel, Enterprise Linux, Enterprise Mrg and 3 more 2024-08-05 N/A
The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.
CVE-2017-17449 2 Linux, Redhat 5 Linux Kernel, Enterprise Linux, Enterprise Mrg and 2 more 2024-08-05 N/A
The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system.
CVE-2017-16939 3 Debian, Linux, Redhat 6 Debian Linux, Linux Kernel, Enterprise Linux and 3 more 2024-08-05 7.8 High
The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages.
CVE-2017-15649 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more 2024-08-05 N/A
net/packet/af_packet.c in the Linux kernel before 4.13.6 allows local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346.
CVE-2017-15265 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Enterprise Mrg and 4 more 2024-08-05 7.0 High
Race condition in the ALSA subsystem in the Linux kernel before 4.13.8 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted /dev/snd/seq ioctl calls, related to sound/core/seq/seq_clientmgr.c and sound/core/seq/seq_ports.c.
CVE-2017-15127 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more 2024-08-05 N/A
