In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Fix potential memory leak in rtw_txq_push_skb() The skb passed to… (CVE-2026-80941)
A memory leak vulnerability in the Linux kernel's wifi driver rtw88 was fixed. The issue occurs because the skb buffer is not freed on an error path in the rtw_txq_push_skb() function, potentially leading to memory exhaustion over time.
AI Analysis
Technical Summary
The Linux kernel's wifi driver rtw88 contained a memory leak vulnerability (CVE-2026-80941) caused by the failure to free the skb buffer in the error path of the rtw_txq_push_skb() function. Specifically, when rtw_hci_tx_write() fails, the skb is expected to be freed, but the error path in rtw_txq_push_skb() does not perform this freeing, leading to a leak when a dequeued skb is passed to rtw_txq_push_skb(). This flaw has been resolved in the Linux kernel.
Potential Impact
This vulnerability can lead to a memory leak in the kernel's wifi driver, which over time could degrade system performance or stability due to memory exhaustion. There is no indication of direct code execution or privilege escalation from this issue.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.
