kernel: The flow_dissector feature allows device tracking

A device tracking vulnerability was found in the flowdissector feature in the Linux kernel. This flaw occurs because the auto flowlabel of the UDP IPv6 packet relies on a 32-bit hashmd value as a secret, and jhash instead of siphash is used. The hashmd value remains the same starting from boot ti...

The vulnerability of the flow_dissector function in Linux operating systems allows a hacker to gain unauthorized access to protected information.

The vulnerability of the flowdissector function in Linux operating systems is related to the use of the hash function jhash instead of siphash. Exploiting this vulnerability can allow a remote attacker to gain unauthorized access to protected information...

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...
