CVE-2018-1118 4 Canonical, Debian, Linux and 1 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2024-11-21 N/A
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
CVE-2018-1094 3 Canonical, Linux, Redhat 7 Ubuntu Linux, Linux Kernel, Enterprise Linux and 4 more 2024-11-21 5.5 Medium
The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted ext4 image.
CVE-2018-1092 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Extras Rt 2024-11-21 N/A
The ext4_iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a root directory with a zero i_links_count, which allows attackers to cause a denial of service (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4 image.
CVE-2018-1087 4 Canonical, Debian, Linux and 1 more 16 Ubuntu Linux, Debian Linux, Linux Kernel and 13 more 2024-11-21 N/A
kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest.
CVE-2018-1068 4 Canonical, Debian, Linux and 1 more 17 Ubuntu Linux, Debian Linux, Linux Kernel and 14 more 2024-11-21 6.7 Medium
A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory.
CVE-2018-19985 4 Debian, Linux, Netapp and 1 more 6 Debian Linux, Linux Kernel, Active Iq Performance Analytics Services and 3 more 2024-11-21 N/A
The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads 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 allows arbitrary read in the kernel address space.
CVE-2018-18690 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 N/A
In the Linux kernel before 4.17, 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 mishandles ATTR_REPLACE operations with conversion of an attr from short to long form.
CVE-2018-18559 2 Linux, Redhat 16 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 13 more 2024-11-21 8.1 High
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-2018-18445 3 Canonical, Linux, Redhat 10 Ubuntu Linux, Linux Kernel, Enterprise Linux and 7 more 2024-11-21 7.8 High
In the Linux kernel 4.14.x, 4.15.x, 4.16.x, 4.17.x, and 4.18.x before 4.18.13, faulty computation of numeric bounds in the BPF verifier permits out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandles 32-bit right shifts.
CVE-2018-18281 4 Canonical, Debian, Linux and 1 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2024-11-21 N/A
Since Linux kernel version 3.2, the mremap() syscall performs 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. This is fixed in the following kernel versions: 4.9.135, 4.14.78, 4.18.16, 4.19.
CVE-2018-17972 4 Canonical, Debian, Linux and 1 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2024-11-21 N/A
An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.
CVE-2018-16885 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Enterprise Linux Server and 1 more 2024-11-21 N/A
A flaw was found in the Linux kernel that allows the userspace to call memcpy_fromiovecend() and similar functions with a zero offset and buffer length which causes the read beyond the buffer boundaries, in certain cases causing a memory access fault and a system halt by accessing invalid memory address. This issue only affects kernel version 3.10.x as shipped with Red Hat Enterprise Linux 7.
CVE-2018-16884 4 Canonical, Debian, Linux and 1 more 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more 2024-11-21 8.0 High
A flaw was found in the Linux kernel's NFS41+ subsystem. 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.
CVE-2018-16871 3 Linux, Netapp, Redhat 31 Linux Kernel, Cloud Backup, H300e and 28 more 2024-11-21 7.5 High
A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost.
CVE-2018-16658 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 N/A
An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status 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.
CVE-2018-15594 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 N/A
arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests.
CVE-2018-14734 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 N/A
drivers/infiniband/core/ucma.c in the Linux kernel through 4.17.11 allows ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allows attackers to cause a denial of service (use-after-free).
CVE-2018-14646 2 Linux, Redhat 10 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 7 more 2024-11-21 N/A
The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service.
CVE-2018-14634 4 Canonical, Linux, Netapp and 1 more 16 Ubuntu Linux, Linux Kernel, Active Iq Performance Analytics Services and 13 more 2024-11-21 N/A
An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable.
CVE-2018-14633 4 Canonical, Debian, Linux and 1 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2024-11-21 7.0 High
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. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable.
