Description
A flaw was found in the Linux kernel's mac80211 wireless subsystem. When wireless mesh proxy paths are removed or expire, the interface path counter is decremented without having been accounted for during path creation. An attacker can exploit this accounting flaw through rapid proxy path churn, driving the counter down and bypassing the maximum mesh path limit. This failure to enforce path limits can lead to excessive resource consumption and a Denial of Service (DoS).
