Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ipv4: iptunnel: Fixed a suspicious RCU usage warning in iptunnelfind The per-netns IP tunnel hash table is protected by the RTNL mutex, and iptunnelfind is only called from the control path where the mutex is acquired. Added a...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: gpio: xilinx: Convert gpiolock to a raw spinlock. Functions related to the irqchip may be called in the context of a raw spinlock. Therefore, we must also use a raw spinlock for our own internal locking mechanisms. This fix...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ice: Fixed the LAG and VF lock dependencies in iceresetvf. The commit fixes the issue where the ice driver acquires the LAG mutex during iceresetvf. This lock acquisition is placed just before acquiring the VF configuration...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: lapbether: ignore ops-locked netdevs Syzkaller managed to trigger a lock dependency in xsknotify via registernetdevice.
