Memory Leak Vulnerability in Linux Kernel Affecting Network Drivers

CVE-2025-39830

What is CVE-2025-39830?

A memory leak has been identified in the Linux kernel related to the error handling process of the hws_pool_buddy_init(). This issue arises when the buddy allocator's cleanup procedure fails to free the memory allocated for the allocator structure itself. To address the problem, a missing kfree() function has been implemented to ensure that all allocated memory is properly released, preventing potential system resource exhaustion and enhancing overall system stability.
