Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mac80211: fixed a use-after-free in CCMP/GCMP RX. When PN checking is performed in mac80211, for fragmentation purposes, we need to copy the PN into the RX struct so that it can be used later for comparison. This is reflected in...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

A list management bug in BSS handling in the mac80211 stack of the Linux kernel versions 5.1 through 5.19.x, prior to 5.19.16, could be exploited by local attackers those capable of injecting WLAN frames to corrupt a linked list and, in turn, potentially execute unauthorized code...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel versions 5.1 through 5.19.x, prior to 5.19.16, could be exploited by local attackers those capable of injecting WLAN frames to trigger use-after-free conditions, potentially allowing them to execute...

kernel: wifi: mac80211: capture fast-RX rate before mesh reuses skb->cb

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This use-after-free vulnerability arises from incorrect handling of fast-RX rate data during mesh processing. This can lead to memory corruption, which an attacker could potentially exploit to cause a system crash denial of service...

kernel: wifi: mac80211: fix MLE defragmentation

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This vulnerability arises from incorrect handling of Multi-Link Element MLE defragmentation. When a reconf or EPCS Enhanced Power Save MLE is present in a non-transmitted profile, the defragmentation routine uses an incorrect pointe...
