CVE-2023-1838

A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in the virtio network subcomponent in the Linux kernel due to a double fget. This issue could allow a local attacker to crash the system, and could lead to a kernel information leak problem.

Mitigation

This flaw can be mitigated by preventing the affected Host kernel accelerator (vhost-net) kernel module from loading during the boot time, ensure the module is added to the blacklist file.
