CVE-2026-42960 Possible cache poisoning via promiscuous records for the authority section

NLnet Labs Unbound up to and including version 1.25.0 is vulnerable to poisoning via promiscuous records for the authority section. Promiscuous RRSets that complement DNS replies in the authority section can be used to trick Unbound to cache such records. If an adversary is able to attach such...

EUVD-2026-31081

NLnet Labs Unbound up to and including version 1.25.0 has a vulnerability in the DNSSEC validator where the code path to consult the negative cache for DS records does not take into account the limit on NSEC3 hash calculations introduced in 1.19.1. This leads to degradation of service during the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Thermal/debugfs: Fixed two locking issues related to the thermal zone debug. With the current locking mechanism for thermal zones in the debugfs code, user space can open the “mitigations” file for a thermal zone before the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: hwmon: Handling failures in registering sensors with thermal zones correctly. If an attempt is made to register a sensor with a thermal zone and it fails, the call to devmthermalzoneofsensorregister may return -ENODEV. This ca...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: btrfs: Zoned – Initialize the zone info of the device for seeding. When performing seeding on a zoned filesystem, it is necessary to initialize the btrfszoneddeviceinfo structure of each zoned device. Otherwise, mounting the...

Astra Linux – Vulnerability in Ansible

A flaw was discovered in the solariszone module from the Ansible Community modules. When setting the name of the zone on the Solaris host, the zone name is checked by listing the process with the ‘ps’ command on the remote machine. An attacker could exploit this flaw by creating a malicious zone...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dm: limiting swapping tables for devices with zone write plugs The dmrevalidatezones function only allows new or previously unzoned devices to call blkrevalidatediskzones. If the device was already zoned, disk-nrzones would alway...
