CVE-2019-18282

The flowdissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash instead of siphash is used. The hashrn...

CVE-2019-18282

CVE-2019-18282 affects the Linux kernel flow_dissector (Linux 4.3–5.x up to 5.3.10). The root cause is that UDP/IPv6 flow labels rely on a 32-bit hashrnd secret, with jhash used instead of siphash, allowing an attacker to infer the secret and track flows. Affected code includes net/core/flow_diss...
