CVE-2025-37872: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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().

Affected products

• Linux Linux Kernel: from 6.8, before 6.12.25 (fixed in 6.12.25); from 6.13, before 6.14.4 (fixed in 6.14.4); version 6.15 only
