CVE-2014-2672 [HIGH] kernel: ath9k: tid->sched race in ath_tx_aggr_sleep()
kernel: ath9k: tid->sched race in ath_tx_aggr_sleep()
Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large amount of network traffic that triggers certain list deletions.
It was found that a remote attacker could use a race condition flaw in the ath_tx_aggr_sleep() function to crash the system by creating large network traffic on the system's Atheros 9k wireless network adapter.
Statement: This issued does not affect Red Hat Enterprise Linux 5 because we do not provide support for Atheros 9k wireless network adapters.

CVE-2014-2672 [HIGH] CVE-2014-2672 kernel: ath9k: tid->sched race in ath_tx_aggr_sleep()
CVE-2014-2672 kernel: ath9k: tid->sched race in ath_tx_aggr_sleep()
We check tid->sched without a lock taken on ath_tx_aggr_sleep(). That is race condition which can result of doing list_del(&tid->list) twice (second time with poisoned list node) and causing a crash.
