How to fix?

Upgrade Chainguard linux-qemu-6.12 to version 6.12.80-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-qemu-6.12 package and not the linux-qemu-6.12 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: Fix error code in iwl_op_mode_dvm_start()

Preserve the error code if iwl_setup_deferred_work() fails. The current code returns ERR_PTR(0) (which is NULL) on this path. I believe the missing error code potentially leads to a use after free involving debugfs.
