CVSS 3.1 Score 6.7 of 10 (medium)
Details
Summary
CVE-2023-6238 is a buffer overflow vulnerability found in the NVM Express (NVMe) driver in the Linux kernel. This vulnerability allows a privileged user to specify a small meta buffer and perform larger Direct Memory Access (DMA) into the same buffer, resulting in overwriting unrelated kernel memory. As a result, random kernel crashes and memory corruption can occur. The affected products include those using the s5UiRj and eCJhJy interfaces. To remediate this vulnerability, it is recommended to apply the latest patches and updates provided by the Linux kernel developers. The potential danger of this vulnerability lies in its ability to allow an attacker with elevated privileges to crash the kernel, potentially leading to system instability or unauthorized access to sensitive information.
