Detailsinfo

A vulnerability was found in Linux Kernel up to 5.4.210/5.10.137/5.15.62/5.19.3. It has been declared as critical. This vulnerability affects an unknown part of the component scsi. The manipulation with an unknown input leads to a buffer overflow vulnerability. The CWE definition for the vulnerability is CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Prevent buffer overflow crashes in debugfs with malformed user input Malformed user input to debugfs results in buffer overflow crashes. Adapt input string lengths to fit within internal buffers, leaving space for NULL terminators.

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2022-50030 since 06/18/2025. The exploitation appears to be easy. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 11/30/2025).
