Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: virtio_ring: Fix data race by tagging
event_triggered as racy for KCSAN syzbot reports a data-race when accessing the event_triggered, here is
the simplified stack when the issue occurred:
================================================================== BUG: KCSAN: data-race in
virtqueue_disable_cb / virtqueue_enable_cb_delayed write to 0xffff8881025bc452 of 1 bytes by task 3288 on

kernel/irq/handle.c:158 handle_irq_event_percpu kernel/irq/handle.c:193 [inline] value changed: 0x01 ->
0x00 ================================================================== When the data race occurs, the
function virtqueue_enable_cb_delayed() sets event_triggered to false, and
virtqueue_disable_cb_split/packed() reads it as false due to the race condition. Since event_triggered is
an unreliable hint used for optimization, this should only cause the driver temporarily suggest that the
device not send an interrupt notification when the event index is used. Fix this KCSAN reported data-race
issue by explicitly tagging the access as data_racy. (CVE-2025-38048)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.263.49 or later.
