Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: ath9khtc: fixed uninitialized values issues Syzbot reported 2 KMSAN bugs in ath9k. All of these bugs are caused by missing field initialization. In htcconnectservice, svcmetalen and pad are not initialized. Based on the code, ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: i2c: imx: preserve error states in the block data length handler When a block read returns an invalid length, such as zero or I2CSMBUSBLOCKMAX, the length handler sets the state to IMXI2CSTATEFAILED. However, i2cimxmasterisr...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mac80211: The issue in ieee80211scanrx involves checking the skb length. This code requires hard-coded compile-time constants for determining the header length check. Instead, a dynamic determination based on the frame type shoul...
