protobuf-java: potential DoS in the parsing procedure for binary data

A flaw was found in protobuf-java. Google Protocol Buffer protobuf-java allows the interleaving of com.google.protobuf.UnknownFieldSet fields. By persuading a victim to open specially-crafted content, a remote attacker could cause a timeout in the ProtobufFuzzer function, resulting in a denial of...

kernel: veth: ensure skb entering GRO are not cloned.

In the Linux kernel, the following vulnerability has been resolved: veth: ensure skb entering GRO are not cloned. After commit d3256efd8e8b "veth: allow enabling NAPI even without XDP", if GRO is enabled on a veth device and TSO is disabled on the peer device, TCP skbs will go through the NAPI...

kernel: bpf, cpumap: Handle skb as well when clean up ptr_ring

An incorrect object type handling flaw was found in the Linux kernel's BPF cpumap implementation in the cleanup path. A local user can trigger this issue by running XDP redirect operations in SKB mode with the cpumap, causing the cleanup code to incorrectly treat socket buffers as XDP frames when...
