Subject: [PATCH 0/4] staging: vc04_services: vchiq-mmal: fix multiple memory safety issues
Date: Sun, 29 Mar 2026 00:21:10 -0600 [thread overview]
Message-ID: <20260329062229.493430-1-sebasjosue84@gmail.com> (raw)
This series fixes four memory safety issues in the MMAL VCHIQ driver
which handles multimedia message passing between the ARM CPU and the
VideoCore GPU on all Raspberry Pi models.
Patch 1: OOB array access in event_to_host_cb()
Patch 2: Missing buffer size check in inline_receive()
Patch 3: Missing bounds check in port_parameter_set()
Patch 4: Integer underflow in port_parameter_get()
All four issues affect both ARM32 and ARM64 Raspberry Pi kernels.
Found through manual source code auditing.
I would like to request separate CVE assignments for each
independently exploitable vulnerability.
