SUSE CVE-2012-6704

The socksetsockopt function in net/core/sock.c in the Linux kernel before 3.5 mishandles negative values of sksndbuf and skrcvbuf, which allows local users to cause a denial of service memory corruption and system crash or possibly have unspecified other impact by leveraging the CAPNETADMIN...

kernel: vmxnet3: use-after-free in vmxnet3_rq_alloc_rx_buf()

A use-after-free flaw was found in vmxnet3rqallocrxbuf in drivers/net/vmxnet3/vmxnet3drv.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 vmxnet3rqcleanupall, which could also lead to ...
