CVE-2026-14178
openGauss 在处理带 NLS 参数的 totimestamp 调用时,totimestampwithfmtnls 会将 nlsfmtstr 保存到 usess-parsercxt.nlsfmtstr。在 seqscan + sort 执行路径下,该字符串原本被分配在 SeqScan 的表达式上下文中;当 SeqScan 完成后,该内存上下文会被 reset,但后续结果输出阶段 timestampout 仍会通过 CheckNlsFormat 访问 usess-parsercxt.nlsfmtstr,导致访问已释放内存。攻击者在具备数据库 SQL 执行权限的情况下,可构造特定...
CVE-2026-14178
openGauss contains a heap-use-after-free in to_timestamp handling when an NLS parameter is used, triggered in the seqscan+sort path by saving nls_fmt_str in the session parser context and referencing it after the SeqScan expression context is reset. Attack requires database SQL execution permissi...
