No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

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.
