CVE-2026-11822, CVE-2026-11824
Summary
Backport upstream security fixes for FTS5 memory corruption vulnerabilities:
CVE-2026-11822
Memory corruption in the FTS5 full-text search extension. Attackers can trigger an out-of-bounds read in fts5LeafSeek() via an attacker-controlled loop bound and a heap buffer overflow write in fts5ChunkIterate() through a crafted continuation page causing an integer underflow.
CVE-2026-11824
Heap-based buffer overflow in the FTS5 full-text search extension. A crafted database with malicious continuation page metadata specifying a szLeaf value smaller than 4 triggers an integer underflow in fts5ChunkIterate().
