# CVE-2026-85150: Null dereference in Red Hat Enterprise Linux 10 > Remote attackers can crash GStreamer RTSP servers or clients via crafted Digest authentication headers, causing denial of service. - **Severity:** High 7.5 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 3 Sep 2026 - **Updated:** 21 Sep 2026 - **Also known as:** ALSA-2026:66460, ALSA-2026:67145, AZL-99891, DEBIAN-CVE-2026-85150, ECHO-5890-0d66-9e2e, GHSA-q4wf-cmpg-8rhf, OESA-2026-3969, RHSA-2026:66460, RHSA-2026:67145, RLSA-2026:66460, RLSA-2026:67145, ROOT-OS-DEBIAN-13-CVE-2026-85150, UBUNTU-CVE-2026-85150 ## What is CVE-2026-85150? CVE-2026-85150 is a high-severity vulnerability in Red Hat Enterprise Linux 10, published on 3 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.

What it is: CVE-2026-85150 is a high-severity vulnerability in Red Hat Enterprise Linux 10, published on 3 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: There is no known exploitation of CVE-2026-85150 in the wild and no public exploit code. Affected product: Red Hat Enterprise Linux 10. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
