GHSA-9FPJ-JHM5-P6H9

Vulnerability from github – Published: 2022-08-26 00:03 – Updated: 2022-08-31 00:00

Details

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.

Severity ?

6.7 (Medium)
