Insufficient validation of attacker-controlled length and size values can bypass bounds checks and cause out-of-bounds heap reads. This can result in application crash, denial of service, or limited information disclosure when untrusted media is processed. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | gst-plugins-ugly1.0 Debian 14 | 1.28.6-1 | [DEBIAN-CVE-2026-19389](https://patchblox.com/security/data/fix/linux/debian-cve-2026-19389.md) | Aug 11, 2026 | | Linux | gstreamer1-plugins-bad-free RHEL 9 | 0:1.22.12-7.el9_8.4 | [RHSA-2026:55865](https://patchblox.com/security/data/fix/linux/rhsa-2026-55865.md) | Aug 19, 2026 | | Linux | gstreamer1-plugins-bad-free almalinux 9 | 1.22.12-7.el9_8.4 | [ALSA-2026:55865](https://patchblox.com/security/data/fix/linux/alsa-2026-55865.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-bad-free ol 9 | 0:1.22.12-7.el9_8.4 | [ELSA-2026-55865](https://patchblox.com/security/data/fix/linux/elsa-2026-55865.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-bad-free rocky 9 | 0:1.22.12-7.el9_8.4 | [RLSA-2026:55865](https://patchblox.com/security/data/fix/linux/rlsa-2026-55865.md) | Aug 18, 2026 | | Linux | gstreamer1-plugins-bad-free-devel RHEL 9 | 0:1.22.12-7.el9_8.4 | [RHSA-2026:55865](https://patchblox.com/security/data/fix/linux/rhsa-2026-55865.md) | Aug 19, 2026 | | Linux | gstreamer1-plugins-bad-free-devel almalinux 9 | 1.22.12-7.el9_8.4 | [ALSA-2026:55865](https://patchblox.com/security/data/fix/linux/alsa-2026-55865.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-bad-free-devel ol 9 | 0:1.22.12-7.el9_8.4 | [ELSA-2026-55865](https://patchblox.com/security/data/fix/linux/elsa-2026-55865.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-bad-free-libs RHEL 9 | 0:1.22.12-7.el9_8.4 | [RHSA-2026:55865](https://patchblox.com/security/data/fix/linux/rhsa-2026-55865.md) | Aug 19, 2026 | | Linux | gstreamer1-plugins-bad-free-libs almalinux 9 | 1.22.12-7.el9_8.4 | [ALSA-2026:55865](https://patchblox.com/security/data/fix/linux/alsa-2026-55865.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-bad-free-libs ol 9 | 0:1.22.12-7.el9_8.4 | [ELSA-2026-55865](https://patchblox.com/security/data/fix/linux/elsa-2026-55865.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-ugly-free RHEL 10 | 1.24.11-1.el10_0.3 | [RHSA-2026:67883](https://patchblox.com/security/data/fix/linux/rhsa-2026-67883.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-ugly-free RHEL 9 | 0:1.22.12-6.el9_8.2 | [RHSA-2026:55865](https://patchblox.com/security/data/fix/linux/rhsa-2026-55865.md) | Aug 19, 2026 | | Linux | gstreamer1-plugins-ugly-free almalinux 10 | 1.26.7-2.el10_2.2 | [ALSA-2026:55435](https://patchblox.com/security/data/fix/linux/alsa-2026-55435.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-ugly-free almalinux 9 | 1.22.12-6.el9_8.2 | [ALSA-2026:55865](https://patchblox.com/security/data/fix/linux/alsa-2026-55865.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-ugly-free ol 10 | 0:1.26.7-2.el10_2.2 | [ELSA-2026-55435](https://patchblox.com/security/data/fix/linux/elsa-2026-55435.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-ugly-free ol 9 | 0:1.22.12-6.el9_8.2 | [ELSA-2026-55865](https://patchblox.com/security/data/fix/linux/elsa-2026-55865.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-ugly-free rocky 10 | 0:1.26.7-2.el10_2.2 | [RLSA-2026:55435](https://patchblox.com/security/data/fix/linux/rlsa-2026-55435.md) | Aug 17, 2026 | | Linux | gstreamer1-plugins-ugly-free rocky 9 | 0:1.22.12-6.el9_8.2 | [RLSA-2026:55865](https://patchblox.com/security/data/fix/linux/rlsa-2026-55865.md) | Aug 18, 2026 | | Linux | gstreamer1.0-plugins-ugly Ubuntu 18.04.6 LTS (bionic) | 1.14.5-0ubuntu1~18.04.1+esm1 | [gstreamer1.0-plugins-ugly 1.14.5-0ubuntu1~18.04.1+esm1](https://patchblox.com/security/data/fix/linux/ubuntu-bionic-gstreamer1.0-plugins-ugly-1.14.5-0ubuntu1-18.04.1-esm1.md) | Aug 9, 2026 | | Linux | gstreamer1.0-plugins-ugly Ubuntu 20.04 LTS (focal) | 1.16.2-2ubuntu0.1~esm1 | [gstreamer1.0-plugins-ugly 1.16.2-2ubuntu0.1~esm1](https://patchblox.com/security/data/fix/linux/ubuntu-focal-gstreamer1.0-plugins-ugly-1.16.2-2ubuntu0.1-esm1.md) | Aug 9, 2026 | | Linux | gstreamer1.0-plugins-ugly Ubuntu 22.04.1 LTS (jammy) | 1.20.1-1ubuntu0.1~esm1 | [gstreamer1.0-plugins-ugly 1.20.1-1ubuntu0.1~esm1](https://patchblox.com/security/data/fix/linux/ubuntu-jammy-gstreamer1.0-plugins-ugly-1.20.1-1ubuntu0.1-esm1.md) | Aug 9, 2026 | | Linux | gstreamer1.0-plugins-ugly Ubuntu 24.04.5 LTS (noble) | 1.24.1-1ubuntu0.1~esm1 | [gstreamer1.0-plugins-ugly 1.24.1-1ubuntu0.1~esm1](https://patchblox.com/security/data/fix/linux/ubuntu-noble-gstreamer1.0-plugins-ugly-1.24.1-1ubuntu0.1-esm1.md) | Aug 9, 2026 | | Linux | gstreamer1.0-plugins-ugly Ubuntu 26.04.1 LTS (resolute) | 1.28.2-1ubuntu0.1~esm1 | [gstreamer1.0-plugins-ugly 1.28.2-1ubuntu0.1~esm1](https://patchblox.com/security/data/fix/linux/ubuntu-resolute-gstreamer1.0-plugins-ugly-1.28.2-1ubuntu0.1-esm1.md) | Aug 9, 2026 | --- Data as of 2026-11-09T01:18:40Z UTC.
