Page history
Changes are dated when recorded; day views use the last saved version from that UTC day, and citations stay fixed.
CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

drm/lima: call drm_mm_init() with a valid allocation range
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:

Fix the issue by moving the lima_vm_create() call after va_start and
va_end are set up.
