CVE-2022-2991 (GCVE-0-2022-2991)

Vulnerability from cvelistv5 – Published: 2022-08-25 17:24 – Updated: 2024-08-03 00:53
VLAI
Summary
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.
