RHEL 8 : kernel-rt (RHSA-2021:4140)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:4140 advisory. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirement...

kernel: accepting fragmented plaintext frames in protected networks

A vulnerability was found in Linux kernel, where the WiFi implementations assemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or...

kernel: Fragmentation cache not cleared on reconnection

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 another device...

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...
