Subject: [PATCH v1 0/2] Skip parsing frames of type UVC_VS_UNDEFINED in
Date: Thu, 7 Nov 2024 14:22:01 +0000 [thread overview]
Message-ID: <20241107142204.1182969-1-bsevens@google.com> (raw)
This can lead to out of bounds writes since frames of this type were not
taken into account when calculating the size of the frames buffer in
uvc_parse_streaming.
I am proposing a series of 2 patches. First patch is very small and
fixes the issue. The idea is to have this patch merged quickly.
The second patch refactors the code into a new uvc_parse_frame function.
I do not have the hardware setup to test this out. The second patch
should definitely be tested.
