CVSS: 8.8EPSS: 0%CPEs: 15EXPL: 0CVE-2020-29569 – Debian Security Advisory 4843-1
https://notcve.org/view.php?id=CVE-2020-29569
15 Dec 2020 — An issue was discovered in the Linux kernel through 5.10.1, as used with Xen through 4.14.x. The Linux kernel PV block backend expects the kernel thread handler to reset ring->xenblkd to NULL when stopped. However, the handler may not have time to run if the frontend quickly toggles between the states connect and disconnect. As a consequence, the block backend may re-use a pointer after it was freed. A misbehaving guest can trigger a dom0 crash by continuously connecting / disconnecting a block frontend. • https://lists.debian.org/debian-lts-announce/2021/02/msg00018.html • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-1971
08 Dec 2020 — The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. • https://github.com/MBHudson/CVE-2020-1971 • CWE-476: NULL Pointer Dereference •
