CVE-2015-4106 6 Canonical, Citrix, Debian and 3 more 8 Ubuntu Linux, Xenserver, Debian Linux and 5 more 2020-09-09 4.6 MEDIUM N/A
QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors.
CVE-2015-7295 3 Debian, Fedoraproject, Qemu 3 Debian Linux, Fedora, Qemu 2020-09-09 5.0 MEDIUM N/A
hw/virtio/virtio.c in the Virtual Network Device (virtio-net) support in QEMU, when big or mergeable receive buffers are not supported, allows remote attackers to cause a denial of service (guest network consumption) via a flood of jumbo frames on the (1) tuntap or (2) macvtap interface.
CVE-2015-8567 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2020-09-09 6.8 MEDIUM 7.7 HIGH
Memory leak in net/vmxnet3.c in QEMU allows remote attackers to cause a denial of service (memory consumption).
CVE-2020-24612 1 Fedoraproject 1 Selinux-policy 2020-09-01 1.9 LOW 4.7 MEDIUM
An issue was discovered in the selinux-policy (aka Reference Policy) package 3.14 through 2020-08-24 because the .config/Yubico directory is mishandled. Consequently, when SELinux is in enforced mode, pam-u2f is not allowed to read the user's U2F configuration file. If configured with the nouserok option (the default when configured by the authselect tool), and that file cannot be read, the second factor is disabled. An attacker with only the knowledge of the password can then log in, bypassing 2FA.
CVE-2014-2678 3 Fedoraproject, Linux, Oracle 3 Fedora, Linux Kernel, Linux 2020-08-28 4.7 MEDIUM N/A
The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports.
CVE-2009-2848 8 Canonical, Fedoraproject, Linux and 5 more 13 Ubuntu Linux, Fedora, Linux Kernel and 10 more 2020-08-28 5.9 MEDIUM N/A
The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.
CVE-2016-7951 2 Fedoraproject, X 2 Fedora, Libxtst 2020-08-27 7.5 HIGH 9.8 CRITICAL
Multiple integer overflows in X.org libXtst before 1.2.3 allow remote X servers to trigger out-of-bounds memory access operations by leveraging the lack of range checks.
CVE-2009-1242 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2020-08-27 4.9 MEDIUM N/A
The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel before 2.6.29.1 on the i386 platform allows guest OS users to cause a denial of service (OOPS) by setting the EFER_LME (aka "Long mode enable") bit in the Extended Feature Enable Register (EFER) model-specific register, which is specific to the x86_64 platform.
CVE-2010-2959 5 Debian, Fedoraproject, Linux and 2 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2020-08-27 7.2 HIGH N/A
Integer overflow in net/can/bcm.c in the Controller Area Network (CAN) implementation in the Linux kernel before 2.6.27.53, 2.6.32.x before 2.6.32.21, 2.6.34.x before 2.6.34.6, and 2.6.35.x before 2.6.35.4 allows attackers to execute arbitrary code or cause a denial of service (system crash) via crafted CAN traffic.
CVE-2008-1375 6 Canonical, Debian, Fedoraproject and 3 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2020-08-26 6.9 MEDIUM N/A
Race condition in the directory notification subsystem (dnotify) in Linux kernel 2.6.x before 2.6.24.6, and 2.6.25 before 2.6.25.1, allows local users to cause a denial of service (OOPS) and possibly gain privileges via unspecified vectors.
CVE-2016-2775 4 Fedoraproject, Hp, Isc and 1 more 9 Fedora, Hp-ux, Bind and 6 more 2020-08-25 4.3 MEDIUM 5.9 MEDIUM
ISC BIND 9.x before 9.9.9-P2, 9.10.x before 9.10.4-P2, and 9.11.x before 9.11.0b2, when lwresd or the named lwres option is enabled, allows remote attackers to cause a denial of service (daemon crash) via a long request that uses the lightweight resolver protocol.
CVE-2019-19578 2 Fedoraproject, Xen 2 Fedora, Xen 2020-08-24 7.2 HIGH 8.8 HIGH
An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to cause a denial of service via degenerate chains of linear pagetables, because of an incorrect fix for CVE-2017-15595. "Linear pagetables" is a technique which involves either pointing a pagetable at itself, or to another pagetable of the same or higher level. Xen has limited support for linear pagetables: A page may either point to itself, or point to another pagetable of the same level (i.e., L2 to L2, L3 to L3, and so on). XSA-240 introduced an additional restriction that limited the "depth" of such chains by allowing pages to either *point to* other pages of the same level, or *be pointed to* by other pages of the same level, but not both. To implement this, we keep track of the number of outstanding times a page points to or is pointed to another page table, to prevent both from happening at the same time. Unfortunately, the original commit introducing this reset this count when resuming validation of a partially-validated pagetable, incorrectly dropping some "linear_pt_entry" counts. If an attacker could engineer such a situation to occur, they might be able to make loops or other arbitrary chains of linear pagetables, as described in XSA-240. A malicious or buggy PV guest may cause the hypervisor to crash, resulting in Denial of Service (DoS) affecting the entire host. Privilege escalation and information leaks cannot be excluded. All versions of Xen are vulnerable. Only x86 systems are affected. Arm systems are not affected. Only x86 PV guests can leverage the vulnerability. x86 HVM and PVH guests cannot leverage the vulnerability. Only systems which have enabled linear pagetables are vulnerable. Systems which have disabled linear pagetables, either by selecting CONFIG_PV_LINEAR_PT=n when building the hypervisor, or adding pv-linear-pt=false on the command-line, are not vulnerable.
CVE-2019-19577 2 Fedoraproject, Xen 2 Fedora, Xen 2020-08-24 7.2 HIGH 7.2 HIGH
An issue was discovered in Xen through 4.12.x allowing x86 AMD HVM guest OS users to cause a denial of service or possibly gain privileges by triggering data-structure access during pagetable-height updates. When running on AMD systems with an IOMMU, Xen attempted to dynamically adapt the number of levels of pagetables (the pagetable height) in the IOMMU according to the guest's address space size. The code to select and update the height had several bugs. Notably, the update was done without taking a lock which is necessary for safe operation. A malicious guest administrator can cause Xen to access data structures while they are being modified, causing Xen to crash. Privilege escalation is thought to be very difficult but cannot be ruled out. Additionally, there is a potential memory leak of 4kb per guest boot, under memory pressure. Only Xen on AMD CPUs is vulnerable. Xen running on Intel CPUs is not vulnerable. ARM systems are not vulnerable. Only systems where guests are given direct access to physical devices are vulnerable. Systems which do not use PCI pass-through are not vulnerable. Only HVM guests can exploit the vulnerability. PV and PVH guests cannot. All versions of Xen with IOMMU support are vulnerable.

A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-db8fd2cde932.
CVE-2019-19055 3 Canonical, Fedoraproject, Linux 3 Ubuntu Linux, Fedora, Linux Kernel 2020-08-24 4.9 MEDIUM 5.5 MEDIUM
** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of this because it occurs on a code path where a successful allocation has already occurred.
CVE-2019-19046 3 Fedoraproject, Linux, Opensuse 3 Fedora, Linux Kernel, Leap 2020-08-24 6.8 MEDIUM 6.5 MEDIUM
