Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A issue was discovered in the Linux kernel before version 6.0.11. Missing validation of the number of channels in the drivers/net/wireless/microchip/wilc1000/cfg80211.c file in the WILC1000 wireless driver can lead to a heap-based buffer overflow when copying the list of operating channels from...

Astra Linux – Vulnerability in Linux

A NULL pointer dereference flaw was discovered in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem, regarding the way the user terminates the LR-WPAN connection. This flaw allows a local user to crash the system. The greatest threat posed by this vulnerability is to system...

Astra Linux – Vulnerability in Linux

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP does not require that received fragments be cleared from memory after reconnecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted usin...

Astra Linux – Vulnerability in Linux

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP does not require that all fragments of a frame be encrypted with the same key. An adversary can exploit this weakness to decrypt selected fragments when another device sends fragmented...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: rfi: fix potential response leaks If the check for the rx payload length fails, or if kmemdup fails, we still need to free the command response. Fix that...

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

A problem with out-of-bound reading was detected in brcmfmac/cfg80211.c within the drivers/net/wireless/broadcom/brcm80211 directory of the Linux kernel. This issue can occur when the associnfo-reqlen data is larger than the size of the buffer, which is defined as WLEXTRABUFMAX, resulting in a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: mt76: mt7921 – Fixed a skb leak caused by missing txs in AMSDU. Txs may be dropped if the frame is aggregated in AMSDU. When this problem occurs, some SKBs are held by the driver, causing the network to stop temporarily. Ev...

Astra Linux – Vulnerability in Wireshark

A NULL pointer exception occurs in the IEEE 802.11 dissector in Wireshark versions 3.4.0 to 3.4.9 and 3.2.0 to 3.2.17, allowing for denial of service through packet injection or with crafted capture files...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: cfg80211: Fixing management registration locking issues The issue with management registration locking was fixed. The list was locked for each wdev, but the cfg80211mgmtregistrationsupdate function iterated over it without holdin...

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...

Astra Linux – Vulnerability in Linux-Firmware

Improper access control in some IntelR PROSet/Wireless WiFi and KillerTM WiFi software may allow a privileged user to potentially enable the escalation of privileges through local access...

Astra Linux – Vulnerability in Linux-Firmware

Improper input validation in some IntelR PROSet/Wireless WiFi and KillerTM WiFi software may allow an authenticated user to potentially enable escalation of privileges via local access...

Astra Linux – Vulnerability in Linux

A issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second or subsequent broadcast fragments even when sent in plaintext and process them as fully unfragmented frames. An adversary can exploit this vulnerability to inject arbitrary...
