Subject: [PATCH v2 0/4] staging: vc04_services: vchiq-mmal: fix multiple memory safety issues
Date: Sun, 29 Mar 2026 01:15:38 -0600	[thread overview]
Message-ID: <20260329071616.507876-1-sebasjosue84@gmail.com> (raw)
In-Reply-To: <20260329062229.493430-1-sebasjosue84@gmail.com>

Changes since v1:
- Reframed patch 1 as hardening rather than security fix (Greg)
- Switched pr_err/pr_warn to ratelimited variants (Greg)
- Added Cc: stable to all patches (Greg)
- Note: dev_err() not used as this file has no struct device access

This series adds defensive bounds checks to the MMAL VCHIQ driver
which handles multimedia message passing between the ARM CPU and the
VideoCore GPU on all Raspberry Pi models.
