Doc Text:
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.

Description OSIDB Bzimport 2025-12-30 13:18:55 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: Fix memory leak in ath11k_peer_rx_frag_setup

crypto_alloc_shash() allocates resources, which should be released by
crypto_free_shash(). When ath11k_peer_find() fails, there has memory
leak. Add missing crypto_free_shash() to fix this.
