Important: kernel

Issue Overview: A flaw was found in the Linux kernels implementation of wifi fragmentation handling. An attacker with the ability to transmit within the wireless transmission range of an access point can abuse a flaw where previous contents of wifi fragments can be unintentionally transmitted to...

CVE-2022-22153

An Insufficient Algorithmic Complexity combined with an Allocation of Resources Without Limits or Throttling vulnerability in the flow processing daemon flowd of Juniper Networks Junos OS on SRX Series and MX Series with SPC3 allows an unauthenticated network attacker to cause latency in transit...

Security Bulletin: This Power System update is being released to address CVE-2018-5391

Summary POWER9: In response to a denial of service vulnerability, a new Power Systems firmware update is being released to address Common Vulnerabilities and Exposures issue number CVE-2018-5391. A remote attacker could use large IP frames to trigger time and calculation expensive calls in the...

Packet Injection

kernel is vulnerable to packet injection. The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext...

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...

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 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...
