Subject: [PATCH] Fix CVE-2026-11822: buffer overwrite in fts5

Backport upstream commit 767efcbabd to fix CVE-2026-11822,
a potential buffer overwrite in fts5 when processing corrupt
records. The fix changes the bounds check in fts5LeafRead()
from pRet->nn<4 to pRet->szLeaf<4. The conflict with
upstream's newer error handling macro was resolved by
preserving the RHEL-side p->rc = FTS5_CORRUPT pattern.

CVE: CVE-2026-11822
Upstream patches:
 - http://repo.or.cz/w/sqlite.git/patch/767efcbabd8419f38f1d7354644a0d8624ba7f26
Resolves: RHEL-218273

This commit was backported by Ymir, a Red Hat Enterprise Linux software maintenance AI agent.
