Описание
A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with normal user privilege to cause a denial of service due to a missing sanity check during cleanup.
Отчет
For the Red Hat Enterprise Linux 8.7 (and higher versions) the patch that resolves the problem already applied (so no need to update then). Similar for the Red Hat Enterprise Linux 9.1 (and higher versions) the patch that resolves the problem already applied. Only Red Hat Enterprise Linux 9.0 affected.
Меры по смягчению последствий
In order to mitigate this issue, prevent the affected code from being loaded by blacklisting the kernel module "vmxnet3". For instructions relating to how to blacklist a kernel module refer to: https://access.redhat.com/solutions/41278
