AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a potential memory leak in the Linux kernel's AMD DRM (Direct Rendering Manager) component. Specifically, the issue occurs when a function returns NULL at the end, causing the clk_src memory not to be properly freed. The patch fixes this by replacing 'free' with 'kfree' to correctly release the allocated memory.
How can this vulnerability impact me? :
A memory leak in the kernel can lead to increased memory usage over time, potentially causing system instability, degraded performance, or crashes if the leak is significant and persistent.
