kernel: reassembling mixed encrypted/plaintext fragments

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...

kernel: Reassembling fragments encrypted under different keys

A flaw was found in the Linux kernel's WiFi implementation. An attacker within the wireless range can abuse a logic flaw in the WiFi implementation by reassembling packets from multiple fragments under different keys, treating them as valid. This flaw allows an attacker to send a fragment under a...

kernel: reassembling encrypted fragments with non-consecutive packet numbers

A vulnerability was found in Linux kernel, where the WiFi implementation reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP...
