{"apiVersion":"1.0","identifier":"CVE-2026-99208","description":"In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Zero OA buffer at allocation ttm_bo_type_kernel BOs are not guaranteed to be zeroed on allocation and may contain data from previously freed pages. Since the OA buffer is mmap-able by userspace, this can expose stale kernel memory contents. Streams opened with DRM_XE_OA_PROPERTY_OA_DISABLED allocate the OA buffer without calling xe_oa_init_oa_buffer(). Zero the buffer at allocation to prevent information disclosure through mmap. The existing zeroing in xe_oa_init_oa_buffer() remains necessary for zero report-id/timestamp detection on enable/re-enable.
