AMD Graphics Driver - out-of-bounds write: MULTI-TENANT ISOLATION: Improper input validation lets a local attacker

Impact

MULTI-TENANT ISOLATION: Improper input validation lets a local attacker write out of bounds through the AMD graphics driver, costing integrity or availability. Out-of-bounds kernel writes reachable from a GPU device handle are the standard escape route out of a GPU container.

Who can reach it

Local, via the graphics driver interface - reachable from a tenant container with a GPU device node.

What to do

Update the AMD graphics driver package and reload the driver or reboot the node.
