CVE-2020-10690

There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptpclock and cdev while resource deallocation. When a high privileged process allocates a ptp device file like /dev/ptpX and voluntarily goes to sleep. During this time if the underlying device ...

CVE-2020-1628

Juniper Networks Junos OS uses the 128.0.0.0/2 subnet for internal communications between the RE and PFEs. It was discovered that packets utilizing these IP addresses may egress an EX4300 switch, leaking configuration information such as heartbeats, kernel versions, etc. out to the Internet,...

VulnCheck KEV: CVE-2018-5391

The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation...

Linux kernel information disclosure vulnerability (CNVD-2020-00266)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. An information disclosure vulnerability exists in Linux kernel 5.2.14 and earlier versions. The vulnerability arises from errors in configuration and other errors in t...

Linux kernel resource management error vulnerability (CNVD-2019-35843)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States.

Linux kernel code issue vulnerability

Linux kernel is the kernel used by Linux, an open source operating system released by the Linux Foundation in the U.S. A code issue vulnerability exists in the sound/usb/line6/driver.c file in versions of Linux kernel prior to 5.1.8. The vulnerability stems from an improperly designed or...

Linux kernel information disclosure vulnerability (CNVD-2019-23988)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. An information disclosure vulnerability exists in Linux kernel versions 4.1 through 4.x and 5.x prior to 5.0.8. The vulnerability arises from errors such as...

kernel: Race condition in sound system can lead to denial of service

In the Linux kernel versions 4.12, 3.10, 2.6, and possibly earlier, a race condition vulnerability exists in the sound system allowing for a potential deadlock and memory corruption due to use-after-free condition and thus denial of service. Due to the nature of the flaw, privilege escalation...

CVE-2019-3901

A race condition in perfeventopen allows local attackers to leak sensitive data from setuid programs. As no relevant locks in particular the credguardmutex are held during the ptracemayaccess call, it is possible for the specified target task to perform an execve syscall with setuid execution...

AZL-6521 CVE-2019-3887 affecting package kernel for versions less than 5.10.78.1-1

A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister MSR access with nested=1 virtualization enabled. In that, L1 guest could access L0's APIC register values via L2 guest, when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash t...
