Description
The vulnerability allows a local attacker to cause a denial of service.
The vulnerability exists due to improper memory management in ieee80211_tx_prepare_skb() when processing transmit skbs. A local attacker can trigger an error path that does not free an skb to cause a denial of service.
The issue affects the first error path where ieee80211_tx_prepare() returns TX_DROP, resulting in inconsistent skb handling compared to the other error paths.
Remediation
Install security update from vendor's repository.
