Aug 4 RESCORED — CVE-2024-47678 (Linux). CVSS 9.4 → 5.5 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
icmp: change the order of rate limits
ICMP messages are ratelimited :
After the blamed commits, the two rate limiters are applied in this order:
1) host wide ratelimit (icmp_global_allow())
2) Per destination ratelimit (inetpeer based)
In order to avoid side-channels attacks, we need to apply
the per destination check first.
This patch makes the following change :
1) icmp_global_allow() checks if the host wide limit is reached.
But credits are not yet consumed. This is deferred to 3)
2) The per destination limit is checked/updated.
This might add a new node in inetpeer tree.
3) icmp_global_consume() consumes tokens if prior operations succeeded.
This means that host wide ratelimit is still effective
in keeping inetpeer tree small even under DDOS.
As a bonus, I removed icmp_global.lock as the fast path
can use a lock-free operation.
