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...

CVE-2026-74336

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. An out-of-bounds read vulnerability exists when parsing the S1G Sub-1 GHz TIM Traffic Indication Map Partial Virtual Bitmap PVB element. Due to an incorrect boundary check, the system can read two bytes beyond the allocated memory f...

CVE-2026-72004

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This issue occurs when the system attempts to copy Wi-Fi band structures, and an error during this process causes a memory resource to not be properly released. This oversight leads to a memory leak within the kernel, which could...

CVE-2026-68470

A flaw was found in the Linux kernel's mac80211 wifi driver. Improper validation of extension-frame layouts before processing received frames could allow a remote attacker to send specially crafted S1G beacon extension frames. This could lead to incorrect memory access when reading network header...

The vulnerability of the function ieee80211_ml_reconfiguration() in the net/mac80211/mlme.c module of the Linux operating system allows a attacker to compromise the integrity of protected information or cause service failures.

The vulnerability of the function ieee80211mlreconfiguration in the net/mac80211/mlme.c module of the Linux operating system is related to the execution of operations outside the buffer in memory. Exploiting this vulnerability could allow a remote attacker to compromise the integrity of protected...
