"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-992443 advisory.

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

    ath11k: fix netdev open race

    Make sure to allocate resources needed before registering the device.

    This specifically avoids having a racing open() trigger a BUG_ON() in
    mod_timer() when ath11k_mac_op_start() is called before the
    mon_reap_timer as been set up.

    I did not see this issue with next-20220310, but I hit it on every probe
    with next-20220511. Perhaps some timing changed in between.

    Here's the backtrace:
