pasid

About this tag
The pasid tag on WindowsForum.com covers Linux kernel security vulnerabilities related to the Process Address Space ID (PASID) in AMD GPU drivers. Discussions focus on race conditions and double-release bugs in the AMDGPU and amdkfd code that can cause kernel oopses and local denial-of-service. Content includes analysis of CVEs such as CVE-2025-40310 and CVE-2022-50303, along with upstream fixes and distribution advisories. The tag is relevant for system administrators, kernel developers, and IT professionals managing AMD GPU-equipped Linux systems who need to understand and apply security patches for PASID-related issues.

  1. CVE-2025-40310: Linux kernel race between AMDGPU and amdkfd causes local DoS

    A recently disclosed Linux kernel vulnerability, tracked as CVE-2025-40310, stems from a race condition between the AMDGPU driver and the AMD Kernel Fusion Driver (amdkfd) during device teardown and VM cleanup. The flaw can allow redundant or concurrent release of a PASID (Process Address Space...

  2. CVE-2022-50303: Linux Kernel Patch Fixes AMD PASID Double Release DoS

    The Linux kernel security record for CVE-2022-50303 closes a small but consequential race-and-error path in the AMD GPU stack: a double release of a compute PASID (process address space identifier) in the drm/amdkfd code that can produce deterministic kernel oopses and sustained...
