https://notcve.org/view.php?id=CVE-2020-25284
The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap rbd block devices, aka CID-f44d04e696fe. El controlador de dispositivo del bloque rbd en el archivo drivers/block/rbd.c en el kernel de Linux versiones hasta 5.8.9, usaba una comprobación incompleta de permisos para acceder a dispositivos rbd, que podrían ser aprovechados por atacantes locales para asignar o desasignar dispositivos de bloque rbd, también se conoce como CID-f44d04e696fe A flaw was found in the capabilities check of the rados block device functionality in the Linux kernel. Incorrect capability checks could alllow a local user with root priviledges (but no capabilities) to add or remove Rados Block Devices from the system. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00021.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f44d04e696feaf13d192d942c4f14ad2e117065a https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html https://lists.debian.org/debian-lts-announce/2020/10/msg00032.html https://lists.debian.org/debian-lts-announce/2020/10/msg00034.html https://twitter.com/grsecurity/ • CWE-732: Incorrect Permission Assignment for Critical Resource CWE-863: Incorrect Authorization •
