| CVE-2018-18710 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2024-11-21 | N/A |
| An issue was discovered in the Linux kernel through 4.19. 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. | ||||
| 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-2018-18688 | 11 Apple, Code-industry, Foxitsoftware and 8 more | 16 Macos, Master Pdf Editor, Foxit Reader and 13 more | 2024-11-21 | 5.3 Medium |
| The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, an Incremental Saving vulnerability exists in multiple products. When an attacker uses the Incremental Saving feature to add pages or annotations, Body Updates are displayed to the user without any action by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects LibreOffice, Master PDF Editor, Nitro Pro, Nitro Reader, Nuance Power PDF Standard, PDF Editor 6 Pro, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, Perfect PDF 10 Premium, and Perfect PDF Reader. | ||||
| 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-2018-18397 | 3 Canonical, Linux, Redhat | 12 Ubuntu Linux, Linux Kernel, Enterprise Linux and 9 more | 2024-11-21 | N/A |
| The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c. | ||||
| CVE-2018-18386 | 3 Canonical, Linux, Redhat | 3 Ubuntu Linux, Linux Kernel, Enterprise Linux | 2024-11-21 | N/A |
| drivers/tty/n_tty.c in the Linux kernel before 4.14.11 allows 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. | ||||
| 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-2018-18021 | 4 Canonical, Debian, Linux and 1 more | 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more | 2024-11-21 | N/A |
| arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes. | ||||
| CVE-2018-17977 | 1 Linux | 1 Linux Kernel | 2024-11-21 | N/A |
| The Linux kernel 4.14.67 mishandles certain interaction among XFRM Netlink messages, IPPROTO_AH packets, and IPPROTO_IP packets, which allows local users to cause a denial of service (memory consumption and system hang) by leveraging root access to execute crafted applications, as demonstrated on CentOS 7. | ||||
| 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-2018-17182 | 5 Canonical, Debian, Linux and 2 more | 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more | 2024-11-21 | 7.8 High |
| An issue was discovered in the Linux kernel through 4.18.8. The vmacache_flush_all function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations. | ||||
| 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-2018-16882 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 8.8 High |
| A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error while processing posted interrupt address, it unmaps the 'pi_desc_page' without resetting 'pi_desc' descriptor address, which is later used in pi_test_and_clear_on(). A guest user/process could use this flaw to crash the host kernel resulting in DoS or potentially gain privileged access to a system. Kernel versions before 4.14.91 and before 4.19.13 are vulnerable. | ||||
| CVE-2018-16880 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 7.0 High |
| A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable. | ||||
| 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-2018-16862 | 4 Canonical, Debian, Linux and 1 more | 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more | 2024-11-21 | N/A |
| A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one. | ||||
| 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-2018-16597 | 4 Linux, Netapp, Opensuse and 1 more | 5 Linux Kernel, Active Iq Performance Analytics Services, Element Software and 2 more | 2024-11-21 | N/A |
| An issue was discovered in the Linux kernel before 4.8. Incorrect access checking in overlayfs mounts could be used by local attackers to modify or truncate files in the underlying filesystem. | ||||
