CVE-2026-90227

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express input/output control ioctl handling. An unprivileged local user could exploit this vulnerability by bypassing access checks in the NVMEIOCTLSUBMITIO function. This allows them to perform unauthorized I/O operations on a...

cve-2025-7771

CVE-2025-7771 — ThrottleStop.sys LPE Proof-of-concept for CVE-2025-7771. ThrottleStop.sys exposes two IOCTL handlers that allow arbitrary physical memory read/write with no access control — any admin process can read or write anywhere in physical RAM. Tested on Windows 10 22H2 and Windows 11 23H2...

kernel: i2c: stub: Reject I2C block transfers with invalid length

A flaw was found in the Linux kernel's i2c-stub driver. A local user with access to the /dev/i2c- device can exploit this vulnerability by issuing an I2C System Management Bus SMBus input/output control ioctl command with a specially crafted block transfer length. This invalid length can cause th...
