CVE-2026-46287

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.0.12-1.1

Description An RTNL assertion warning occurs in the txgbe driver for copper NICs with an external PHY during module removal. This happens because the phylink disconnect phy() function is called without the necessary locking. The issue is triggered when the driver executes the txgbe remove() and txgbe remove phy() functions, leading to a failure in the RTNL (Routing Netlink) assertion within the phylink disconnect phy() function.

Recommendations Update to version 7.0.12-1.1 or later.
