kernel: net: potential information leak when ubuf backed skbs are skb_zerocopy()ied
Use-after-free vulnerability in the nfqnlzcopy function in net/netfilter/nfnetlinkqueuecore.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation. NOTE: the affected code was moved to the...
Kernel: filter: prevent nla extensions to peek beyond the end of the message
The BPFSANCNLATTRNEST extension implementation in the skrunfilter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service over-read and system crash via crafted BPF instructions. NOTE:...
kernel: netfilter: nf_conntrack_dccp: incorrect skb_header_pointer API usages
net/netfilter/nfconntrackprotodccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service system crash or possibly execute arbitrary code via a DCCP packet that triggers a call to the 1 dccpnew, 2 dccppacket, or 3...
