Redis before 8.8.0, in the unusual case where an authenticated attacker can execute RESTORE, allows remote code execution via a RESTORE payload where the same NACK (pending entry) is referenced by more than one consumer, because deleting both consumers via XGROUP DELCONSUMER leads to a double free. NOTE: this issue exists because of an incomplete fix for CVE-2026-25243.

CVE-2026-55653 是 OpenSSH 中的一个 double free 漏洞，位于 Diffie-Hellman Group Exchange (DH-GEX) 客户端路径中。当客户端在 FIPS 模式下处理攻击者控制的 DH-GEX 组参数时，已知组验证过程中会触发 double free，导致客户端进程异常终止，造成拒绝服务（DoS）。攻击者需要诱导客户端连接至恶意的 SSH 服务器，并发送特制的 DH-GEX 组参数。该漏洞影响 OpenSSH 的 FIPS 模式下的客户端，且无需认证即可远程触发，但需要用户交互（连接恶意服务器）。CVSS 评分为 4.3（中等），攻击复杂度低，但仅影响可用性。目前无已知在野利用或已被列入 KEV。建议用户升级至包含此漏洞补丁的 OpenSSH 版本，并避免连接到不可信的 SSH 服务器以降低风险。
💡 影响/原因: OpenSSH 被广泛使用，此漏洞允许恶意 SSH 服务器导致客户端崩溃，造成拒绝服务，影响系统可用性。

Rizin 是一个类 Unix 的逆向工程框架和命令行工具集。该漏洞存在于 librz/core/cmd/cmd_search.c 文件的 byte_pattern_search() 函数中，由于指针所有权声明错误，导致发生了双重释放（double free）漏洞。攻击者可能通过诱导用户使用特制的输入触发该漏洞，在特定条件下造成程序崩溃或内存损坏，从而可能引发拒绝服务或信息泄露。虽然 CVSS 评分为 3.3（低危），但考虑到 Rizin 在逆向工程和安全分析中的广泛使用，任何稳定性问题都可能导致分析工作中断。官方已通过提交 045fff363b42b8a6dda8ad5229c29ec3267e7dbe 修复此问题，建议用户升级到包含该修复的版本（如 Rizin 0.7.2 或更高版本）。临时缓解措施包括限制对 Rizin 工具的网络暴露，避免处理不可信的输入文件，以及确保运行环境受控。目前未发现该漏洞已被在野利用的证据。
💡 影响/原因: 该漏洞可能导致 Rizin 工具崩溃，影响逆向工程工作的连续性，尽管低危，但修复简单，建议及时打补丁。
FreeRDP is a free implementation of the Remote Desktop Protocol.

## Summary `Sender::send` in `src/lib.rs` contains an `unsafe` block in the `DISCONNECTED` arm that transmutes a **raw pointer** (`*mut Producer`) into the bytes of a **value-level** `Consumer`. The author's intent, visible in the surrounding comment at lines 386-390, was a value transmute. The shipped code is one level of indirection off. The resulting `Consumer` has its internal `Arc::ptr` set

libbabl 0.1.62 contains a broken double free detection vulnerability that allows attackers to bypass memory safety checks by exploiting signature overwriting in freed chunks. Attackers can call babl_free() twice on the same pointer without triggering detection, as libc's malloc metadata overwrites babl's signature field upon freeing, enabling potential memory corruption and code execution.

`InlineVec::clear()` and `SerVec::clear()` in `rkyv` were not panic-safe. Both functions iterate over their elements and call `drop_in_place` on each, updating `self.len` only *after* the loop. If an element's `Drop` implementation panics during the loop, `self.len` is left at its original value. A subsequent invocation of `clear()` on the same container then re-visits the already-freed elements:
