UBUNTU-CVE-2026-45970: Ubuntu/linux vulnerability

Q: Which Ubuntu kernel package families are listed as affected?

The affected package families listed are ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-aws-fips, and ubuntu/linux-azure-fips.

Q: How can this issue appear in system diagnostics?

The supplied crash report shows a KASAN null-pointer-dereference or general protection fault involving rlb_arp_recv in the bonding module. The report occurred while the ping process was running and identifies the ALB receive path.

Q: Does the supplied advisory identify a fixed package version?

No fixed Ubuntu package version is provided in the supplied data.

Published May 27, 2026

In the Linux kernel, the following vulnerability has been resolved: bonding: alb: fix UAF in rlbarprecv during bond up/down The ALB RX path may access rxhashtbl concurrently with bond teardown. During rapid bond up/down cycles, rlbdeinitialize() frees rxhashtbl while RX handlers are still running, leading to a null pointer dereference detected by KASAN. However, the root cause is that rlbarprecv() can still be accessed after setting recvprobe to NULL, which is actually a use-after-free (UAF) issue. That is the reason for using the referenced commit in the Fixes tag.

Fix this by setting recvprobe to NULL and then calling synchronizenet() to wait for any concurrent RX processing to finish. This ensures that no RX handler can access rxhashtbl after it is freed in bondalbdeinitialize().
