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

In the Linux kernel, the following vulnerabilities have been resolved: l2tp: The correct message length must be passed to ip6.AppendData. l2tpip6sendmsg needs to avoid accounting for the transport header twice when splicing more data into an already partially-occupied skbuff. To address this issu...

Astra Linux – Vulnerability in Qemu

A bug in QEMU could cause a guest I/O operation that is normally directed to an arbitrary disk offset to be directed instead to offset 0. This could potentially overwrite the VM’s boot code. For example, this could be exploited by L2 guests who have a virtual disk vdiskL2 stored on the virtual di...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: l2tp: All race conditions in l2tptunnelregister have been fixed. The code within l2tptunnelregister is problematic in several ways: 1. It modifies the tunnel socket after it is published. 2. It calls setupudptunnelsock on an...

CVE-2026-68398

CVE-2026-68398 is a Linux kernel UAF in PPPoL2TP: pppol2tp_recv() can dereference a freed internal PPP channel when a bound-but-unattached channel is closed, leading to potential local escalation. The fix defers freeing the channel to an RCU callback (call_rcu) to ensure a grace period for in-fli...
