CVE-2026-98179: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix rmmio iounmap skipped on device removal amdgpu_pci_remove() calls drm_dev_unplug() before fini_sw(), so drm_dev_enter() is already false there and the iounmap() guarded by it is skipped. This .remove path runs on both hot-unplug and plain rmmod, so the register BAR ioremap mapping leaks one instance per unload. Unmap rmmio unconditionally (guard only on non-NULL) and drop the now unused idx. (cherry picked from commit dd6f86a97260e5207d3329ad03aa89fdad61b1e6)
