The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005160 advisory.

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

    Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc

    A NULL sock pointer is passed into l2cap_sock_alloc() when it is called     from l2cap_sock_new_connection_cb() and the error handling paths should     also be aware of it.

    Seemingly a more elegant solution would be to swap bt_sock_alloc() and     l2cap_chan_create() calls since they are not interdependent to that moment     but then l2cap_chan_create() adds the soon to be deallocated and still     dummy-initialized channel to the global list accessible by many L2CAP     paths. The channel would be removed from the list in short period of time     but be a bit more straight-forward here and just check for NULL instead of     changing the order of function calls.

    Found by Linux Verification Center (linuxtesting.org) with SVACE static     analysis tool.
