CVE-2026-53086 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix racing timeout handler The bcmgenet_timeout handler tries to take down all tx queues when a single queue times out. This is over zealous and causes many race conditions with queues that are still chugging along. Instead lets only restart the timed out queue.
A race condition vulnerability has been identified in the Linux kernel's handling of Ethernet transmission timeouts for Broadcom BCMGENET drivers. When a single transmission queue times out, the timeout handler attempts to take down all transmission queues, which is excessive and leads to race conditions with queues that are still active. The vulnerability is present in the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been addressed.
