rsyscall

摘要 rsyscall 是一个库，它为不断增长的 Linux 系统调用子集提供了接口。 该接口具有以下特性： 进程无关 ：所有系统调用都作为进程对象上的方法进行调用，这些对象可以引用“本地”进程或我们控制下的其他进程，甚至可能位于远程主机上。 类型安全 ：许多 Linux API 的约束通常留给用户代码来强制执行，而现在它们在类型系统中被明确表示。 底层 ：任何可以通过底层 Linux API 实现的操作，都可以通过 rsyscall 实现；没有禁止或限制的操作。 有关 rsyscall 背后的概念和动机的更多细节，请阅读file:docs/conceptual.org概念介绍。 快速开...

hw: amd: Instruction raise #VC exception at exit

A vulnerability was found in AMD SEV-SNP, where a malicious hypervisor can potentially break confidentiality and integrity of SEV-SNP on Linux guests by injecting interrupts. An attacker can inject interrupt 0x80, which is used by Linux for legacy 32-bit system calls, and arbitrarily change the...

CVE-2019-18684

Sudo through 1.8.29 allows local users to escalate to root if they have write access to file descriptor 3 of the sudo process. This occurs because of a race condition between determining a uid, and the setresuid and openat system calls. The attacker can write "ALL ALL=ALL NOPASSWD:ALL" to...
