A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows an attacker to gain filesystem-level control of the dump directory while privileged event scripts ar

该漏洞存在于 abrt-dbus D-Bus 服务的 ChownProblemDir 方法中。abrt 是自动错误报告工具，用于捕获和分析应用程序崩溃。其 D-Bus 服务提供接口供本地用户触发操作。ChownProblemDir 方法本应更改转储目录中所有文件的所有权为调用者 UID，但在实现上存在竞态条件：该方法以只读模式（DD_OPEN_READONLY）打开转储目录，然后调用 dd_chown 更改所有权。然而，在 post-create 事件处理器持有写锁时，ChownProblemDir 仍能成功执行。攻击者可以利用这一窗口，在特权事件脚本运行期间获取对转储目录的文件系统级控制。成功利用后，攻击者可以读取、修改或删除该目录下的任意文件，甚至可能提升权限或干扰系统正常错误报告流程。CVSS 评分为 7.0（高），攻击向量为本地，需要低权限且攻击复杂度较高，但无需用户交互，影响机密性、完整性和可用性。目前未发现该漏洞已入 KEV 或在野利用的证据。受影响产品未具体列出，但通常涉及 Linux 系统中安装了 abrt 的发行版（如 Fedora、RHEL 等）。建议用户尽快关注厂商提供的安全更新，并限制不必要的本地用户访问。

`PyCFunction::new_closure` (and the temporary `new_closure_bound` complement in the 0.21–0.22 series) required the supplied closure to be `Send + 'static` but not `Sync`. The resulting `PyCFunction` is a Python callable that can be invoked from any Python thread, which means the closure may be called concurrently from multiple threads, and needs a `Sync` bound to prevent possible data races.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, an attacker who can connect to a magick -distribute-cache service can hijack a file descriptor in the server process when a race condition is met. This issue has been patched in versions 6.9.13-48 and 7.1.2-23.

pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.1, src/log.c contains a process-wide static pointer that is written on every PAM invocation with the address of a stack-local variable. This violates the PAM re-entrancy requirement and creates a data race when the PAM stack is invoked concurrently from multiple threads. This vulnerability is fixed in 0

Algernon is a small self-contained pure-Go web server. Prior to 1.17.6, in engine/luahandler.go, the sync.RWMutex protecting LoadCommonFunctions is released before L.Push() and L.PCall() execute.

The Go race detector confirms this immediately under modest concurrency

Sparx Pro Cloud Server is vulnerable to a Race Condition in the /data_api/dl_internal_artifact.php endpoint.

The adjustments made for XSA-379 as well as those subsequently becoming XSA-387 still left a race window, when a HVM or PVH guest does a grant table version change from v2 to v1 in parallel with mapping the status page(s) via XENMEM_add_to_physmap. Some of the status pages may then be freed while mappings of them would still be inserted into the guest's secondary (P2M) page tables.

NetBSD prior to commit ec8451e contains a race condition vulnerability in cryptodev_op() within the opencrypto subsystem that allows local attackers to trigger a double-free condition by concurrently issuing CIOCCRYPT operations on the same session identifier on SMP systems.
