CVE-2026-98345
Estado: RecibidaSin puntuar—
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: check IP header size in cfg80211_classify8021d()
A frame that looks like IP can be transmitted, but be too short, so the DS field is read incorrectly:
Use skb_header_pointer() like the MPLS case.
