Memory Leak in Linux Kernel's TXGBE Driver

CVE-2025-37872

Summary

In the Linux kernel, a memory leak occurs in the TXGBE driver during the initialization path. When the txgbe_sw_init() function is called, it allocates memory for wx->rss_key within wx_init_rss_key(). However, if an error arises during the invocation of txgbe_probe(), this allocated memory is not properly released, leading to memory leaks. The updated implementation ensures that both the rss_key and wx->mac_table are deallocated appropriately during the error handling phase, preventing conditions that could further lead to double free issues when mac_table allocation fails.
