Description OSIDB Bzimport 2025-06-18 12:04:37 UTC
In the Linux kernel, the following vulnerability has been resolved:

ath11k: fix missing skb drop on htc_tx_completion error

On htc_tx_completion error the skb is not dropped. This is wrong since
the completion_handler logic expect the skb to be consumed anyway even
when an error is triggered. Not freeing the skb on error is a memory
leak since the skb won't be freed anywere else. Correctly free the
packet on eid >= ATH11K_HTC_EP_COUNT before returning.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-01208-QCAHKSWPL_SILICONZ-1
