(CVE-2026-18798) * Fixed heap buffer overflow in CMS key unwrapping. (CVE-2026-63072) * Fixed invalid pointer dereference in CMP server via crafted protectionAlg. (CVE-2026-63076) * Fixed unbounded memory growth in QUIC server incoming channel queue. (CVE-2026-14456) * Fixed RPK server signature algorithm selection being able to dereference a missing certificate. (CVE-2026-14457) * Fixed excessive memory use buffering DTLS records for a future epoch. (CVE-2026-54874) * Fixed untrusted Sender DN being used as a format string in CMP response validation. (CVE-2026-63073) * Fixed CMP indefinite cache growth of extraCerts. (CVE-2026-63074) * Fixed QUIC ACK-only packet retention being able to cause memory exhaustion. (CVE-2026-63075) * Fixed possibility of AEAD forgeries with empty ciphertext when using EVP_Cipher(). (CVE-2026-75803) * Fixed checking of authentication tags for empty ciphertexts for AEAD ciphers in CCM cipher mode.

Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
