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.
A buffer overrun flaw exists in the Linux kernel when the strlen function is used on name fields in V1 wmfw files. This issue results in a loss of system availability.
Отчет
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-787: Out-of-bounds Write vulnerability and downgrades the severity of this particular CVE from Moderate to Low. The platform enforces hardening guidelines to apply the most restrictive settings necessary for operational requirements. Baseline configurations and system controls ensure secure software settings, while least functionality reduces the attack surface by disabling unauthorized services and ports. The environment employs IPS/IDS and antimalware solutions to detect and prevent malicious code exploiting out-of-bounds write vulnerabilities, using mechanisms such as file integrity monitoring and patch management. Robust input validation and error handling ensure all user inputs are thoroughly validated, preventing instability, data exposure, or privilege escalation. Finally, the platform uses memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) to strengthen resilience against out-of-bounds write exploits.
Меры по смягчению последствий
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.
