Linux Kernel Security Vulnerabilities
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of zero-copy page fixing in the rdsmessagezcopyfromuser function. This failure does n...
CVE-2026-33278
NLnet Labs Unbound 1.19.1 up to and including version 1.25.0 has a vulnerability in the DNSSEC validator that enables denial of service and possible remote code execution as a result of deep copying a data structure and erroneously overwriting a destination pointer. An adversary can exploit the...

CVE-2026-33278
NLnet Labs Unbound 1.19.1–1.25.0 contains a vulnerability in the DNSSEC validator: during NSEC3-budget–driven validation suspensions, Unbound deep-copies response messages and a struct-assignment overwrites the destination pointer with the source pointer. After freeing the sub-query region, the v...

Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: perf/dwcpcie: fixed duplicate PCIDEV devices. During the platformdeviceregister function, the incorrect use of structdevice as platformdata resulted in a kmemdup operation on the PCIDEV structure. Even worse, accessing the...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: vfio: Split migration operations from main device operations The vfio core checks whether the driver sets certain migration operations e.g., setstate/getstate, and accordingly calls those operations. However, currently, the ml...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: In the bpf code, there is a fix for a use-after-free of sk-sksocket in skpsockverdictdataready. The syzbot reported a use-after-free of the sk-sksocket of an AFUNIX socket in skpsockverdictdataready. 0 In the unixstreamsendmsg...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: Tracing: Fixed the issue with copylinklist updates when the “copyTracemarker” option is enabled for an instance. When this option is enabled, any data written to /sys/kernel/tracing/tracemarker is also copied into the buffer o...
