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

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...

CVE-2026-74700

A flaw was found in the Linux kernel's traffic control classifier application programming interface API. A race condition can occur during the destruction of locked classifiers, specifically within the tcnewtfilter function. This race allows an unlocked classifier's request to prematurely decreme...

CVE-2026-74620

This Linux kernel vulnerability affects the net/sched subsystem, specifically the act_gact and act_police traffic control actions. The fallback control actions (TCA_GACT_PROB.paction and TCA_POLICE_RESULT) bypass the range check in tcf_action_check_ctrlact(), allowing user space to store TC_ACT_C...

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,...

CVE-2026-74382
