Publication date 23 April 2017
Last updated 25 August 2025
Ubuntu priority
Cvss 3 Severity Score
Description
drivers/char/virtio_console.c in the Linux kernel 4.9.x and 4.10.x before 4.10.12 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory corruption) or possibly have unspecified other impact by leveraging use of more than one virtual page for a DMA scatterlist.
From the Ubuntu Security Team
It was discovered that the virtio console driver in the Linux kernel improperly handled memory. A local attacker could use this to cause a denial of service (system crash).
