kernel: inotify: Avoid reporting event with invalid wd
A race condition was found in the Linux kernel's inotify subsystem. When inotifyfreeingmark races with inotifyhandleinodeevent, the event handler may read imark-wd after it has been reset to -1. This causes an invalid watch descriptor value of -1 to be reported to userspace applications,...
kernel: x86/tdx: Fix "in-kernel MMIO" check
A flaw was found in the Linux kernel. Userspace can deceive the kernel into performing MMIO Memory-Mapped IO operations in TDX Trust Domain Extensions on its behalf, allowing a VE Virtualization Exception to be incorrectly handled as a in-kernel MMIO operation...
Zephyr 安全漏洞
Zephyr is an extensible real-time operating system RTOS open-sourced by Zephyr. A security vulnerability exists in Zephyr that stems from a contention condition in the entry point of a system call, which could lead to elevation of privilege by a malicious userspace process...
PT-2025-46349
Name of the Vulnerable Software and Affected Versions versions prior to 2025-9408 Description A race condition exists during system call entry on Cortex M processors, potentially allowing privilege escalation for malicious user space processes. It is possible this issue may also affect Cortex R a...
USN-7862-2: Linux kernel vulnerability
Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this t...
