AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a memory leak in the Linux kernel's platform/x86/amd code, specifically in the wbrf_record() function.
The issue occurs because a temporary buffer allocated with kcalloc() is not freed if the function acpi_evaluate_dsm() fails, causing memory to be leaked in the error handling path.
The fix involves explicitly freeing this temporary buffer when acpi_evaluate_dsm() fails to prevent the memory leak.
How can this vulnerability impact me? :
This vulnerability can lead to a memory leak in the Linux kernel, which may cause increased memory usage over time.
If exploited or triggered repeatedly, it could degrade system performance or potentially lead to system instability due to exhaustion of available memory.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
