CVE-2022-2991

Published: 25 August 2022

A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability.

From the Ubuntu Security Team

Lucas Leong discovered that the LightNVM subsystem in the Linux kernel did not properly handle data lengths in certain situations. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
