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 Linux kernel that stems from not using arrayindexnospec for indexes from clients, which could lead to a speculative execution side-channel...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: Prevent Spectre v1 exploits in sysrtas. Smatch warns: arch/powerpc/kernel/rtas.c:1932 dosysrtas warning: potential Spectre issue with ‘args args’ r local variable. The ‘nargs’ and ‘nret’ locals originate from a...

kernel: gpio: prevent potential speculation leaks in gpio_device_get_desc()

A flaw was found in the Linux kernel's General Purpose Input/Output GPIO subsystem. A local user can exploit this vulnerability by providing an out-of-range offset to the gpioioctl function. This can lead to a speculative read of memory outside the intended GPIO descriptor array, potentially...

kernel: protect the fetch of ->fd[fd] in do_dup2() from mispredictions

In the Linux kernel, the following vulnerability has been resolved: protect the fetch of -fdfd in dodup2 from mispredictions both callers have verified that fd is not greater than -maxfds; however, misprediction might end up with tofree = fdt-fdfd; being speculatively executed. That's wrong for t...
