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...
