CVE-2023-4387

A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in VMware’s vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a kernel information leak problem.

Mitigation

Mitigation for this issue is to skip loading the affected module "vmxnet3" onto the system until the fix is available, this can be done by a blacklist mechanism which will ensure the driver is not loaded at the boot time.

How do I blacklist a kernel module to prevent it from loading automatically?
