Summary
sqlite3 vulnerabilities
Details

It was discovered that SQLite did not properly handle NULL pointer dereferences in the Session Extension when applying a corrupt changeset. An attacker could possibly use this issue to cause SQLite to crash, resulting in a denial of service. (CVE-2026-50812)

It was discovered that SQLite had a buffer overread in the Session Extension when processing a corrupt changeset. An attacker could possibly use this issue to obtain sensitive information. (CVE-2026-50813)
