Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from a buffer overflow issue during the processing of dm-ioctl commands. This vulnerability could lead...

The vulnerability of the lookup_ioctl() function in the drivers/md/dm-ioctl.c module of the support for multiple devices (RAID and LVM) in the Linux kernel allows a attacker to cause a service failure.

The vulnerability of the lookupioctl function in the drivers/md/dm-ioctl.c module of the Linux support driver for multiple devices such as RAID and LVM is related to unvalidated array indexing. Exploiting this vulnerability could allow an attacker to cause a service failure...

kernel: dm ioctl: prevent potential spectre v1 gadget

A vulnerability was found in the Linux kernel's dm-ioctl interface in the lookupioctl function, which accepts a user-provided cmd value that is used to index the ioctls array directly. This issue could lead to an out-of-bounds access if the CPU speculatively executes the array access before cmd i...
