Summary

In the Linux kernel, the following vulnerability has been resolved: vmxnet3: disable rx data ring on dma allocation failure When vmxnet3_rq_create() fails to allocate memory for rq->data_ring.base, the subsequent call to vmxnet3_rq_destroy_all_rxdataring does not reset rq->data_ring.desc_size for the data ring that failed, which presumably causes the hypervisor to reference it on packet reception. To fix this bug, rq->data_ring.desc_size needs to be set to 0 to tell the hypervisor to disable this feature. [ 95.436876] kernel BUG at net/core/skbuff.c:207! [ 95.439074] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI [ 95.440411] CPU: 7 PID: 0 Comm: swapper/7 Not tainted 6.9.3-dirty #1 [ 95.441558] Hardware name: VMware, Inc.
