- Introduction of mseal — The Linux Kernel documentation
In a nutshell, mseal blocks certain mm syscall from modifying some of VMA’s attributes, such as protection bits (RWX) Sealed mappings doesn’t mean the memory is immutable As Jann Horn pointed out in [3], there are still a few ways to write to RO memory, which is, in a way, by design
- LWN：mseal() 以及后续方案！ - CSDN博客
Jeff Xu提出了新增一个名为 mseal() 的系统调用的提案，该系统调用将允许应用程序阻止对选定内存映射（memory mapping）的修改。 这有助于阻止用户空间应用程序对某些类型的攻击；一些其他操作系统已经具备了这种功能。
- Linux新syscall：mseal，传统shellcode的克星 - 华为云社区
最近，Linux引入了一个名叫mseal的新系统调用，这个功能就像给内存加了一把“安全锁”，从根源上增加了系统的防护能力。 它的作用是什么呢？ 就是“锁死”特定内存区域的权限变化，不让攻击者有可趁之机。
- A deep dive into Linux’s new mseal syscall - The Trail of Bits Blog
If you love exploit mitigations, you may have heard of a new system call named mseal landing into the Linux kernel’s 6 10 release, providing a protection called “memory sealing ” Beyond notes from the authors, very little information about this mitigation exists In this blog post, we’ll explain what this syscall is, including […]

- mseal 简介 — Linux 内核文档 - Linux 内核
int mseal(void * addr, size_t len, unsigned long flags) addr len: 虚拟内存地址范围。 addr len 设置的地址范围必须满足 起始地址必须位于已分配的 VMA 中。 起始地址必须是页对齐的。 结束地址 (addr + len) 必须位于已分配的 VMA 中。 起始地址和结束地址之间

- Linux 6. 10 合并了 Mseal - 偏执的码农
Mseal 是一个旨在提高系统安全性和稳定性的重要组件，它通过实施更强大的内核密封机制，有效保护了系统的关键部分免受恶意攻击和数据泄露的威胁。 Mseal 的引入将为 Linux 用户带来更加可靠的操作体验，同时也增强了系统对潜在漏洞和攻击的抵抗能力。
- Mseal in Linux: An un-hackable solution? - DEV Community
A new Linux kernel feature, mseal, is at the center of this focus It introduces new protections for memory pages, aiming to make life harder for hackers who exploit memory vulnerabilities But like many innovations, mseal has sparked considerable debate among developers, including Linux’s own Linus Torvalds Here’s a look at mseal, the
