CVE-2025-22012

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-22012
In the Linux kernel, the following vulnerability has been resolved: Revert "arm64: dts: qcom: sdm845: Affirm IDR0.CCTW on apps_smmu" There are reports that the pagetable walker cache coherency is not a given across the spectrum of SDM845/850 devices, leading to lock-ups and resets. It works fine on some devices (like the Dragonboard 845c, but not so much on the Lenovo Yoga C630). This unfortunately looks like a fluke in firmware development, where likely somewhere in the vast hypervisor stack, a change to accommodate for this was only introduced after the initial software release (which often serves as a baseline for products). Revert the change to avoid additional guesswork around crashes. This reverts commit 6b31a9744b8726c69bb0af290f8475a368a4b805.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Revertir "arm64: dts: qcom: sdm845: Affirm IDR0.CCTW en apps_smmu". Hay informes de que la coherencia de la caché del pagetable walker no es constante en todos los dispositivos SDM845/850, lo que provoca bloqueos y reinicios. Funciona correctamente en algunos dispositivos (como el Dragonboard 845c, pero no tanto en el Lenovo Yoga C630). Lamentablemente, esto parece ser un fallo en el desarrollo del firmware, ya que, probablemente en algún lugar de la vasta pila de hipervisores, se introdujo un cambio para adaptarlo después del lanzamiento inicial del software (que suele servir como base para los productos). Revertir el cambio para evitar conjeturas adicionales sobre fallos. Esto revierte el commit 6b31a9744b8726c69bb0af290f8475a368a4b805.
