22 Oct 2020 — An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users can cause a denial of service (host OS hang) via a high rate of events to dom0, aka CID-e99502f76271. Se detectó un problema en el kernel de Linux versiones hasta 5.9.1, como es usado con Xen versiones hasta 4.14.x.

22 Oct 2020 — An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5.

CVSS: 5.1EPSS: 0%CPEs: 5EXPL: 0CVE-2020-16120 – Unprivileged overlay + shiftfs read access
https://notcve.org/view.php?id=CVE-2020-16120
14 Oct 2020 — Overlayfs did not properly perform permission checking when copying up files in an overlayfs and could be exploited from within a user namespace, if, for example, unprivileged user namespaces were allowed. It was possible to have a file not readable by an unprivileged user to be copied to a mountpoint controlled by the user, like a removable device. This was introduced in kernel version 4.19 by commit d1d04ef ("ovl: stack file ops"). This was fixed in kernel version 5.8 by commits 56230d9 ("ovl: verify perm... • https://git.kernel.org/linus/05acefb4872dae89e772729efb194af754c877e8 • CWE-266: Incorrect Privilege Assignment •

06 Oct 2020 — A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
