Description
The CVE Program describes this issue as:
In the Linux kernel, the following vulnerability has been resolved: firmware: cs_dsp: Use strnlen() on name fields in V1 wmfw files Use strnlen() instead of strlen() on the algorithm and coefficient name string arrays in V1 wmfw files. In V1 wmfw files the name is a NUL-terminated string in a fixed-size array. cs_dsp should protect against overrunning the array if the NUL terminator is missing.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Common Vulnerability Scoring System (CVSS) Score Details
Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
| Red Hat | NVD | |
|---|---|---|
CVSS v3 Base Score | 5.2 | N/A |
Attack Vector | Local | N/A |
Attack Complexity | High | N/A |
Privileges Required | High | N/A |
User Interaction | None | N/A |
Scope | Unchanged | N/A |
Confidentiality Impact | Low | N/A |
Integrity Impact | Low | N/A |
Availability Impact | High | N/A |

Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
