bind9 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.10
- Ubuntu 25.04
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in Bind.
Software Description:
- bind9: Internet Domain Name Server
Details:
Zuyao Xu and Xiang Li discovered that Bind incorrectly handled certain
malformed DNSKEY records. A remote attacker could possibly use this issue
to cause Bind to consume resources, resulting in a denial of service.
(CVE-2025-8677)
Yuxiao Wu, Yunyi Zhang, Baojun Liu, and Haixin Duan discovered that Bind
incorrectly accepted certain records from answers. A remote attacker could
possibly use this issue to perform a cache poisoning attack.
(CVE-2025-40778)
Amit Klein and Omer Ben Simhon discovered that Bind used a weak PRNG. A
remote attacker could possibly use this issue to perform a cache poisoning
attack. (CVE-2025-40780)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 25.10
bind9 1:9.20.11-1ubuntu2.1
Ubuntu 25.04
bind9 1:9.20.11-0ubuntu0.2
Ubuntu 24.04 LTS
bind9 1:9.18.39-0ubuntu0.24.04.2
Ubuntu 22.04 LTS
bind9 1:9.18.39-0ubuntu0.22.04.2
In general, a standard system update will make all the necessary changes.

==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems
- linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems
Details:
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- GPU drivers;
- Network drivers;
- Netlink;
(CVE-2024-26700, CVE-2025-38727, CVE-2023-52593, CVE-2024-26896)

After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
