In the Linux kernel, the following vulnerability has been resolved: Wifi: iwlwifi: mvm: Pause TCM when the firmware is stopped Ignoring this issue will cause us to send a host command to the transport module while the firmware is not active, which will trigger a WARNING. bad state = 0 WARNING: CP...

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...

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 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...
