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

In the Linux kernel before version 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allowed an unprivileged user to trigger a denial of service system crash through a crafted traffic control configuration set up using the "tc qdisc" and "tc class" commands. This issue affect...

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

In the Linux kernel, the following vulnerability has been resolved: net/sched: accept TCASTAB only for root qdisc Most qdiscs maintain their backlog using qdiscpktlenskb on the assumption it is invariant between the enqueue and dequeue handlers. Unfortunately syzbot can crash a host rather easily...

In the Linux kernel, the following vulnerability has been resolved: Networks: hns3: Fixed a deadlock issue that occurred during the reset process when configuring tc. During the reset process, configuring tc can lead to a deadlock. The sequence of events is as follows: 1. pf reset start 2. setup ...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsapi: Remove blockcb from driverlist before freeing it. The error handler of tcfblockBind frees the entire bo-cblist when an error occurs. However, by that time, instances of flowblockCB are already in the driverlist...

kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle

A flaw was found in the Linux kernel's traffic control TC classifier application programming interface API. The tcfqeventhandle function does not properly handle a consumed socket buffer skb when it is processed by the defragmentation engine. This can lead to a Use-After-Free UAF vulnerability,...

The vulnerability of the flow_change() function in the net/sched/cls_flow.c module of the net/sched/traffic control subsystem in the Linux operating system allows a attacker to cause a service failure.

The vulnerability of the flowchange function in the net/sched/clsflow.c module of the net/sched subsystem of the Linux operating system’s kernel is related to the pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...

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

A flaw was discovered in the Linux kernel’s Traffic Control TC subsystem. Using a specific networking configuration—redirecting egress packets to ingress using the TC “mirred” action—a local unprivileged user could trigger a CPU soft lockup ABBA deadlock when the transport protocol in use TCP or...
