The vulnerability (CVE-2025-13601) involves an integer overflow in the g_escape_uri_string() function of the glib2 library, causing a heap-based buffer overflow due to incorrect buffer size calculation when escaping strings with many characters needing escaping. This can result in memory corruption, crashes, or potentially arbitrary code execution. The Red Hat advisory RHSA-2026:7461 updates glib2 RPM packages (version 2.88.0-1.1.hum1) for aarch64 and x86_64 architectures as part of a bug fix and enhancement update for Red Hat Hardened Images. The advisory references multiple related CVEs but does not explicitly confirm a fix for CVE-2025-13601 or others. Mitigation options are either unavailable or insufficient per Red Hat's criteria. The vulnerability is categorized under CWE-190 (Integer Overflow or Wraparound) and has a Red Hat CVSS v3 score of 7.7 (High impact) though no official CVSS score is provided in this advisory.

The integer overflow vulnerability can cause heap-based buffer overflows leading to memory corruption, application crashes, or denial of service. It may also enable attackers to execute arbitrary code or bypass protection mechanisms if exploited. The advisory notes high integrity and availability impacts, including potential modification of memory and resource exhaustion. However, no known exploits in the wild are reported. The vulnerability affects Red Hat Hardened Images using the glib2 library on aarch64 and x86_64 architectures.

The Red Hat advisory does not confirm an official patch or fix availability for this vulnerability at this time. Mitigation options are either not available or do not meet Red Hat's criteria for ease of use, deployment, or stability. Users should monitor Red Hat's official errata and security advisories for updates and apply any future patches promptly. Customers with a Technical Account Manager (TAM) can consult directly for tailored guidance. No immediate workaround is provided in the advisory.
