CVE-2026-11822

Name	CVE-2026-11822
Description	SQLite before 3.53.2 contains memory corruption vulnerabilities in the FTS5 full-text search extension that allow attackers to cause process crashes, memory exhaustion, or arbitrary code execution by supplying a crafted database with malformed FTS5 page data. 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, exploitable when an FTS5 MATCH query is executed against the malicious database.
Source	CVE (at NVD; CERT, ENISA, LWN, oss-sec, fulldisc, Debian ELTS, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
