Upgrade Echo:latest linux-6.12 to version 6.12.107-1~deb12u1 or higher.

See How to fix? for Echo:latest relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
ata: pata_sl82c105: fix bridge revision use-after-free
pci_get_slot() returns a referenced PCI device. Commit 44c10138fd4b ("PCI: Change all drivers to use pci_device->revision") replaced a configuration-space read with direct access to the cached revision field, but left that access after pci_dev_put(). The bridge may therefore be freed before its revision is read.
Read the revision before dropping the reference.
