USN-8954-1CVE-2026-85091zlib vulnerability Executive summary A flaw in zlib, a widely used data-compression library in Ubuntu, could let an attacker crash programs or possibly run code if they supply specially crafted input. The advisory does not give a severity rating, but it describes the impact as denial of service or arbitrary code execution. Canonical recommends applying the standard system update, which contains fixed zlib package versions for Ubuntu 26.10, 26.04 LTS, and 24.04 LTS. Technical summary The advisory describes a heap buffer overflow in zlib triggered through certain non-blocking write operations, reported by Ali Firas. An attacker could possibly exploit it to cause denial of service or arbitrary code execution, and the advisory does not state the required attack preconditions. The fixed packages are 1:1.3.dfsg+really1.3.2-3ubuntu1.1 for 26.10, 1:1.3.dfsg+really1.3.1-1ubuntu3.2 for 26.04 LTS, and 1:1.3.dfsg-3.1ubuntu2.3 for 24.04 LTS, covering zlib1g, zlib1g-dev, and related lib32z1, lib64z1, and libx32z1 packages. The advisory references CVE-2026-85091. No workaround, CVSS score, or exploitation-in-the-wild information is stated, and no detection guidance is provided.
