CVE-2017-3196
PCAUSA Rawether framework does not properly validate BPF data, allowing a crafted malicious BPF program to perform operations on memory outside of its typical bounds on the driver's receipt of network packets.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.70%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
