Linux Kernel Vulnerability in WiFi MAC80211 Component

CVE-2026-98325

What is CVE-2026-98325?

A vulnerability was identified in the Linux kernel's WiFi MAC80211 subsystem, where the failure paths in the TX info setup were not properly managed. This oversight caused potential leaks and failure reports to userspace were inadequately handled. The fix involved early initialization of skb->cb[], which enables the use of ieee80211_free_txskb() to rectify the issue. By correcting the handling of failed SKB elements, the patch enhances the code's robustness and unifies error handling in ieee80211_skb_resize() functions.
