Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

SQLite 3.54.0 之前的版本在 R-Tree 扩展中存在一个释放后使用（use-after-free）漏洞。攻击者可通过操纵 %_node 影子表，诱使应用程序访问已被释放的堆内存。具体而言，攻击者可提供一个数据库，其中 %_node 表声明为 WITHOUT ROWID，或设置了 RAISE(IGNORE) 触发器，导致 nodeWrite() 函数将节点哈希为 0，进而在节点分裂后引发进程崩溃。

Vulnerability Title

SQLite before 3.54.0 Use-After-Free in R-Tree nodeWrite()

Source: CVE Program / CVE List V5

Vulnerability Description

SQLite before 3.54.0 contains a use-after-free vulnerability in the R-Tree extension that allows attackers to make applications use freed heap memory by manipulating the %_node shadow table. Attackers can supply a database declaring %_node WITHOUT ROWID or with a RAISE(IGNORE) trigger so nodeWrite() hashes nodes as 0, crashing the process after node splits.
