Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9831 vulnerabilities reference this CWE, most recent first.

GHSA-V555-5G3C-VQ2X

Vulnerability from github – Published: 2026-06-30 15:30 – Updated: 2026-06-30 15:30
VLAI
Details

openGauss 在处理带 NLS 参数的 to_timestamp 调用时,to_timestamp_with_fmt_nls() 会将 nls_fmt_str 保存到 u_sess->parser_cxt.nls_fmt_str。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 timestamp_out() 仍会通过 CheckNlsFormat() 访问 u_sess->parser_cxt.nls_fmt_str,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 to_timestamp(..., ..., nlsparam) 查询触发 heap-use-after-free。在 ASan/Memcheck 环境下表现为数据库服务退出;在实际运行环境中可能造成后端进程异常退出,影响数据库服务可用性,形成拒绝服务风险。该问题在openGauss-server-7.0.0-RC1版本和openGauss-server-7.0.0-RC2版本存在,目前已在openGauss-server-7.0.0-RC3版本修复。由于 openGauss-server-7.0.0-RC1版本和openGauss-server-7.0.0-RC2均为创新版本,不会发布针对性补丁包,涉及版本升级至 openGauss-server-7.0.0-RC3或更新版本即可。

In the Linux kernel, the following vulnerability has been resolved:

cifs: Fix warning and UAF when destroy the MR list

If the MR allocate failed, the MR recovery work not initialized and list not cleared. Then will be warning and UAF when release the MR:

Let's initialize the MR recovery work before MR allocate to prevent the warning, remove the MRs from the list to prevent the UAF.

GHSA-V5C4-8MX9-G6X5

Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-05-30 12:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

gfs2: Fix slab-use-after-free in qd_put

Commit a475c5dd16e5 ("gfs2: Free quota data objects synchronously") started freeing quota data objects during filesystem shutdown instead of putting them back onto the LRU list, but it failed to remove these objects from the LRU list, causing LRU list corruption. This caused use-after-free when the shrinker (gfs2_qd_shrink_scan) tried to access already-freed objects on the LRU list.

Fix this by removing qd objects from the LRU list before freeing them in qd_put().

Initial fix from Deepanshu Kartikey kartikey406@gmail.com.

Implementation

Strategy: Attack Surface Reduction

When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.

No CAPEC attack patterns related to this CWE.
