CVE-2026-98829 wifi: mac80211: drop oversized fragments to avoid extra_len overflow

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: drop oversized fragments to avoid extralen overflow In ieee80211rxhdefragment, fragment payloads are accumulated into entry-extralen as subsequent fragments arrive: entry-extralen += rx-skb-len; When the final...

CVE-2026-98829

The Linux kernel contains a vulnerability in the mac80211 component where oversized fragments can cause an extra_len overflow . The root cause is that entry->extra_len was narrowed from unsigned int to u16 to reduce memory footprint. When a sequence of large fragments exceeds 65535 bytes, the ...

CVE-2020-26147

A flaw was found in ieee80211rxhdefragment in net/mac80211/rx.c in the Linux Kernel's WiFi implementation. This vulnerability can be abused to inject packets or exfiltrate selected fragments when another device sends fragmented frames, and the WEP, CCMP, or GCMP data-confidentiality protocol is...
