Описание

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.

Меры по смягчению последствий

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? https://access.redhat.com/solutions/41278
