NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-150200_24_126-default package and not the kernel-livepatch-5_3_18-150200_24_126-default package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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.
