CVE-2020-29568

An issue was discovered in Xen through 4.14.x. Some OSes such as Linux, FreeBSD, and NetBSD are processing watch events using a single thread. If the events are received faster than the thread is able to handle, they will get queued. As the queue is unbounded, a guest may be able to trigger an OO...

CVE-2020-29568

CVE-2020-29568 affects Xen frontends/backends (Xen 4.14.x and older) where watch events are processed by a single thread. If events arrive faster than handling, the unbounded queue can exhaust backend memory, allowing a guest to trigger an OOM in the dom0 backend. The Xen issue is described in mu...

CVE-2020-25689

CVE-2020-25689 : In WildFly, all versions up to 21.0.0.Final exhibit a memory-leak in the host-controller when reconnection attempts loop, causing new connections to be created but not properly closed. This can trigger an Out of Memory (OOM) condition and denial of service, primarily affecting av...

CVE-2020-25689

A memory leak flaw was found in WildFly in all versions up to 21.0.0.Final, where host-controller tries to reconnect in a loop, generating new connections which are not properly closed while not able to connect to domain-controller. This flaw allows an attacker to cause an Out of memory OOM issue...

CVE-2020-10781

A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hotadd file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user...

CVE-2020-10781

CVE-2020-10781 affects the Linux kernel ZRAM module: a local attacker who can read /sys/class/zram-control/hot_add can create ZRAM device nodes in /dev, and repeated reads can allocated memory and trigger OOM killer, potentially making the system inoperable.
