CVE-2026-51290

Summary

SQLite 3.41 has a use-after-free vulnerability in the shared cache lock management logic of the btree module. The program frees a BtLock structure without removing the node from the linked list. Subsequent linked list traversal accesses the released memory, which can lead to denial of service and sensitive memory information disclosure.
