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 •

CVE-2020-29374 – Kernel Live Patch Security Notice LSN-0075-1
https://notcve.org/view.php?id=CVE-2020-29374
28 Nov 2020 — An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58. Se detectó un problema en el kernel de Linux versiones anteriores a 5.7.3, relacionado con los archivos mm/gup.c y mm/huge_memory.c.

CVE-2020-25645 – kernel: Geneve/IPsec traffic may be unencrypted between two Geneve endpoints
https://notcve.org/view.php?id=CVE-2020-25645
13 Oct 2020 — A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. Se encontró un fallo en el kernel de Linux en versiones anteriores a 5.9-rc7. El tráfico entre dos endpoints Geneve puede no estar cifrado cuando I... • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00035.html • CWE-319: Cleartext Transmission of Sensitive Information •
