CVE-2025-37872 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: txgbe: fix memory leak in txgbe_probe() error path When txgbe_sw_init() is called, memory is allocated for wx->rss_key in wx_init_rss_key(). However, in txgbe_probe() function, the subsequent error paths after txgbe_sw_init() don't free the rss_key. Fix that by freeing it in error path along with wx->mac_table. Also change the label to which execution jumps when txgbe_sw_init() fails, because otherwise, it could lead to a double free for rss_key, when the mac_table allocation fails in wx_sw_init().
A memory leak vulnerability has been identified in the Linux kernel's TXGBE network driver. When the function 'txgbe_sw_init()' is called, memory is allocated for the RSS key. However, if 'txgbe_sw_init()' encounters an error, the allocated memory for the RSS key is not freed, leading to a memory leak. This vulnerability has been addressed by ensuring that the RSS key is properly freed in the error path, along with the MAC table allocation.
