CVE-2026-100071

The Linux kernel is vulnerable to a memory leak in the net: hsr component. The issue occurs during a device setup failure when the hsr_dev_finalize() function fails after a lower-device RX handler has been registered. Specifically, frames received during this window can learn dynamic nodes into n...
