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 the MCTP driver failing to release the USB device reference when detection fails, resulting in a...

CVE-2026-43251

A flaw was found in the Linux kernel's Human Interface Device HID prodikeys driver. A local attacker can exploit this vulnerability by connecting a specially crafted Universal Serial Bus USB device. This device can send a malicious report descriptor, bypassing a necessary check and causing a null...
