AI Analysis
Technical Summary
Red Hat Product Security issued an advisory (RHSA-2026:0268) for PostgreSQL in Red Hat Enterprise Linux 9.6 Extended Update Support addressing two vulnerabilities: CVE-2025-12817, where the CREATE STATISTICS command does not verify schema CREATE privileges, potentially allowing unauthorized schema statistics creation; and CVE-2025-12818, where the libpq client library undersizes memory allocations due to integer wraparound, which could lead to memory corruption or related issues. The advisory provides updated PostgreSQL packages to fix these vulnerabilities. No CVSS score is provided by Red Hat, but the impact is rated as moderate. The advisory includes detailed package updates and references for remediation.
Potential Impact
The first vulnerability (CVE-2025-12817) could allow users without proper schema CREATE privileges to create statistics, potentially leading to unauthorized database metadata manipulation. The second vulnerability (CVE-2025-12818) involves libpq undersizing allocations due to integer wraparound, which may cause memory corruption or instability in client applications using libpq. Both issues have a moderate security impact rating by Red Hat. There are no known exploits in the wild at the time of the advisory.
Mitigation Recommendations
Red Hat has released updated PostgreSQL packages for Red Hat Enterprise Linux 9.6 Extended Update Support that address these vulnerabilities. Users should apply these official updates as described in the Red Hat advisory RHSA-2026:0268 and the referenced article https://access.redhat.com/articles/11258. Applying these updates will remediate the issues. No additional mitigation steps are specified or required beyond applying the vendor-provided patches.
