CVE-2022-50186: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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

Affected products

• Linux Linux Kernel: from 5.17, before 5.18.18 (fixed in 5.18.18); from 5.19, before 5.19.2 (fixed in 5.19.2)
