In the Linux kernel, the following vulnerability has been resolved: bonding: fix the program leak when XDP is replaced We need to release the reference on the old BPF prog, whether we are going to no-prog, or replacing the prog with another. Spotted by AI while running tests for the propagation...

CVE-2026-98966

The Linux kernel contained a vulnerability within the bonding module where BPF programs were leaked when XDP was replaced. The issue caused leaked programs to accumulate during propagation series tests. This vulnerability has been resolved by ensuring the kernel releases the reference on the old ...

EUVD-2026-108862

In the Linux kernel, the following vulnerability has been resolved: net: lan966x: restore RX state on reload failure lan966xfdmareload backs up rx-pagepool and rx-fdma before reallocating the RX resources for the new MTU. If the allocation fails, the restore path puts these fields back before...

CVE-2026-98906

The Linux kernel contains a vulnerability in the lan966x driver where a failed RX resource reallocation during an MTU change results in an inconsistent state. Specifically, while the driver backs up rx->page_pool and rx->fdma, it fails to restore rx->page_order and rx->max_mtu on fail...
