Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 6.0.15/6.1.1. This issue affects an unknown part. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/qm - increase the memory of local variables Increase the buffer to prevent stack overflow by fuzz test. The maximum length of the qos configuration buffer is 256 bytes. Currently, the value of the 'val buffer' is only 32 bytes. The sscanf does not check the dest memory length. So the 'val buffer' may stack overflow.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2022-50407 since 09/17/2025. The exploitation is known to be easy. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 12/11/2025).

The vulnerability scanner Nessus provides a plugin with the ID 265493 (Linux Distros Unpatched Vulnerability : CVE-2022-50407), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 6.0.16 or 6.1.2 eliminates this vulnerability. Applying the patch 34c4f8ad45b4ea814c7ecc3f23a2d292959d5a52/fc521abb6ee4b8f06fdfc52646140dab6a2ed334/3efe90af4c0c46c58dba1b306de142827153d9c0 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.

The vulnerability is also documented in the databases at Tenable (265493) and CERT Bund (WID-SEC-2025-2092). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
