Resolved Date: Dec 22, 2022
Found In Version: 10.17.41.1
Severity: Standard
Applicable for: Wind River Linux LTS 17
Component/s: Kernel
The flow_dissector 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 hashmd value as a secret, and because jhash (instead of siphash) is used. The hashmd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.
