Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the powerpc64/ftrace module not handling the unpatched function entry case, which could lead to a module...

kernel: s390/idle: mark arch_cpu_idle() noinstr

A kernel warning vulnerability was found in the s390 architecture idle handling in the Linux kernel. The archcpuidle function was not marked as noinstr no instrumentation, causing RCU and tracing warnings when ftrace is enabled. This can trigger kernel warnings and potential issues with tracing i...
