CVE-2026-64145: In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: fix dma_buffer leak on bus acquire

A memory leak vulnerability exists in the Linux kernel's wilc1000 WiFi driver where a buffer allocated with kmalloc (a memory allocation function) is not properly freed when the bus acquire operation fails early in the firmware download process. The problem occurs because an early error path uses a direct return statement instead of going through the cleanup code that frees the buffer.
