Vulnerability from fkie_nvd - Published: 2026-09-17 17:18 - Updated: 2026-09-17 17:18
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/lima: call drm_mm_init() with a valid allocation range
lima_vm_create() is currently run before va_start and va_end are set up,
meaning they are both 0. lima_vm_create() runs drm_mm_init() with them
as arguments for the allocator, and if DRM_DEBUG_MM is enabled the
DRM_MM_BUG_ON check in drm_mm_init then fires, as seen here on
exynos4412-odroid-u2:
[ 1.736297] ------------[ cut here ]------------
[ 1.740370] kernel BUG at drivers/gpu/drm/drm_mm.c:931!
[ 1.745574] Internal error: Oops - BUG: 0 [#1] SMP ARM
[ 1.750697] Modules linked in:

[ 1.763372] Hardware name: Samsung Exynos (Flattened Device Tree)
[ 1.769446] Workqueue: events_unbound deferred_probe_work_func
[ 1.775261] PC is at drm_mm_init+0x9c/0xa4
[ 1.779339] LR is at lima_vm_create+0x144/0x17c
[ ... ]
Fix the issue by moving the lima_vm_create() call after va_start and
va_end are set up.
