Vulnerability from fkie_nvd - Published: 2026-09-03 13:06 - Updated: 2026-09-03 13:06
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
Revert "drm/amdgpu: fix aperture mapping leak"
devres teardown is LIFO. The aperture devres node was registered after
the DRM device node, so devres_release_all() unmaps the aperture before
the DRM device release callback fires amdgpu_device_fini_sw(). IP
sw_fini callbacks (e.g. vcn_v4_0_sw_fini) write to fw_shared through a
pointer derived from aper_base_kaddr, causing a kernel page fault on
probe failure / rollback:
BUG: unable to handle page fault ... PMD 0
RIP: vcn_v4_0_sw_fini+0x7b/0x170 [amdgpu]
Call Trace:
amdgpu_device_fini_sw
amdgpu_driver_release_kms
devm_drm_dev_init_release
devres_release_all
This reverts commit d871e99879cb5fd1fa798b006b4888887e63a17a.
(cherry picked from commit 336e0cd576817ac64a4b394ca2b3680029f3e37f)
