Astra Linux - уязвимость в linux-5.10, linux

Guests running on Arm can cause Denial of Service DoS attacks on Dom0 through PV devices. When mapping memory pages of guests on Arm, Dom0 uses an rbtree to keep track of the foreign mappings. The update of this rbtree does not always occur completely with the relevant lock held, resulting in a...

Astra Linux - уязвимость в linux-5.10, linux

Several Linux PV device frontends are vulnerable to attacks by backends that use grant table interfaces to remove access rights from resources. This can lead to potential data leaks, data corruption by malicious backends, and denial of service attacks. The backends that use these interfaces may n...

Linux Distros Unpatched Vulnerability : CVE-2022-33744

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of tha...

Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held resulting in a small race window which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0 e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages.
