A flaw was found in SQLite. A use-after-free vulnerability in the expression evaluation logic, specifically within the sqlite3ReleaseTempReg and exprComputeOperands functions, allows a remote attacker to exploit the system. By supplying a malicious SQL statement, an attacker can cause a denial of service, leak sensitive information, or potentially execute arbitrary code.

Description OSIDB Bzimport 2026-07-27 16:01:22 UTC 
SQLite 3.41 has a use-after-free vulnerability exists in the expression evaluation logic. The sqlite3ReleaseTempReg function improperly releases temporary register resources, and the subsequent exprComputeOperands function continues to access the already freed register memory. By supplying a malicious SQL statement, a remote attacker can exploit this flaw to cause denial of service, leak sensitive information, or potentially execute arbitrary code on the affected system.
