Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: wcn36xx – Fix for OOB read from short trigger BA firmware response The length of the firmware response is only checked against sizeofrsp 20 bytes. However, when candidatecnt is greater than or equal to 1, a 22-byte candidat...

kernel: wifi: iwlwifi: mld: validate sta_mask before ffs() in BA session handlers

A flaw was found in the Linux kernel's iwlwifi Intel Wireless WiFi driver. This vulnerability allows an attacker to cause an out-of-bounds memory access in the WiFi Block Acknowledgement BA session handlers. This occurs when the stamask value is zero, leading to an incorrect station ID calculatio...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: mac80211: Fixed the issue where tidtx was used after its free in the BA session stop routine. The function ieee80211stoptxbacb passes tidtx to kfreercu through ieee80211removetidtx, and then reads tidtx-ndp after releasing...

CVE-2026-74489

A flaw was found in the Linux kernel's mac80211 component, which manages Wi-Fi Wireless Fidelity networking. This use-after-free vulnerability occurs during the stopping of a Block Acknowledgement BA session. An attacker within the same network segment could exploit this by triggering the BA...
