Denial Of Service (DoS)

systemtap is vulnerable to denial of service. An invalid pointer read flaw was found in the way SystemTap handled malformed debugging information in DWARF format. When SystemTap unprivileged mode was enabled, an unprivileged user in the stapusr group could use this flaw to crash the system or,...

Information Disclosure

kvm is vulnerable to information disclosure. The vulnerability exists as it was found that some structure padding and reserved fields in certain data structures in QEMU-KVM were not initialized properly before being copied to user-space. A privileged host user with access to "/dev/kvm" could use...

Arbitrary Memory Read

The Linux kernel is vulnerable to arbitrary memory read. A flaw in the IPv6 socket option handling allows a local user to read arbitrary kernel memory...

LSN-0065-1: Kernel Live Patch Security Notice

Andrew Honig reported a flaw in the way KVM Kernel-based Virtual Machine emulated the IOAPIC. A privileged guest user could exploit this flaw to read host memory or cause a denial of service crash the host. CVE-2013-1798 It was discovered that the KVM implementation in the Linux kernel, when...

CVE-2020-1625

The kernel memory usage represented as "temp" via 'show system virtual-memory' may constantly increase when Integrated Routing and Bridging IRB is configured with multiple underlay physical interfaces, and one interface flaps. This memory leak can affect running daemons processes, leading to an...

CVE-2020-1625 Junos OS: Kernel memory leak in virtual-memory due to interface flaps

The kernel memory usage represented as "temp" via 'show system virtual-memory' may constantly increase when Integrated Routing and Bridging IRB is configured with multiple underlay physical interfaces, and one interface flaps. This memory leak can affect running daemons processes, leading to an...

CVE-2020-1625

CVE-2020-1625 describes a kernel memory leak in Junos OS virtual-memory (temp) when IRB is configured with multiple underlay interfaces and one interface flaps, causing DoS through escalating temp memory usage. Affected Junos OS versions span multiple branches (e.g., 16.1, 17.1, 17.2, 17.3, 17.4,...

Samsung Mobile Device Buffer Overflow Vulnerability (CNVD-2020-32806)

Android is a Linux-based open source operating system jointly developed by Google Inc. and the Open Handheld Alliance OHA for short. A buffer overflow vulnerability exists in Samsung mobile devices, which can be exploited by attackers to cause kernel memory corruption...

CVE-2019-3892

A race condition was found between mmgetnotzero/gettaskmm when core dumping tasks. A local attacker is able to exploit race condition where locking of semaphore would allow an attacker to leak kernel memory to userspace...

UBUNTU-CVE-2020-11494

An issue was discovered in slcbump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It allows attackers to read uninitialized canframe data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIGINITSTACKALL, aka CID-b9258a2cece4...

CVE-2020-8835

In the Linux kernel 5.5.0 and newer, the bpf verifier kernel/bpf/verifier.c did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the...
