Description
A flaw was found in the Linux kernel's ath11k Wi-Fi driver. This memory leak vulnerability occurs when the ath11k_peer_find() function fails to properly release cryptographic resources. An attacker on the adjacent network with low privileges could exploit this, leading to a gradual reduction in available memory. This can ultimately cause a Denial of Service (DoS) on the affected system.
