CVE-2022-0854

Published: 23 March 2022

A memory leak flaw was found in the Linux kernel’s DMA subsystem, in the way a user calls DMA_FROM_DEVICE. This flaw allows a local user to read random memory from the kernel space.

From the Ubuntu Security Team

It was discovered that the DMA subsystem in the Linux kernel did not properly ensure bounce buffers were completely overwritten by the DMA device. A local attacker could use this to expose sensitive information (kernel memory).
