CVE-2026-50812: n/a
CVE-2026-50812 is a vulnerability in the SQLite Session Extension affecting SQLite version 3.53.1 and trunk builds before a specific commit. It involves a NULL pointer dereference triggered by supplying a malformed changeset blob, causing a denial of service when the function sqlite3changeset_apply_v3() processes corrupt data. No patch or official remediation information is currently available.
AI Analysis
Technical Summary
This vulnerability arises from a NULL pointer dereference in the SQLite Session Extension. When sqlite3changeset_apply_v3() applies a malformed changeset blob, it may call sqlite3_value_type() with a NULL pointer, leading to a denial of service. The affected versions include SQLite 3.53.1 and trunk builds prior to commit e807d4e3798efd53. There is no CVSS score or vendor advisory indicating patch availability or remediation status.
Potential Impact
An attacker capable of supplying a malformed changeset blob can cause the SQLite process to crash, resulting in a denial of service. There is no indication of code execution or data corruption beyond service disruption.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted or malformed changeset blobs in the SQLite Session Extension.
