linux-toradex.git/drivers/firmware/sigma.c, branch v3.0.79 Linux kernel for Apalis and Colibri modules firmware: Sigma: Fix endianess issues 2011-12-09T16:52:39+00:00 Lars-Peter Clausen lars@metafoo.de 2011-11-28T08:44:16+00:00 f90312c8cf03b2294f6840c7dc01236838896acc commit bda63586bc5929e97288cdb371bb6456504867ed upstream. Currently the SigmaDSP firmware loader only works correctly on little-endian systems. Fix this by using the proper endianess conversion functions.

The firmware header is not part of the CRC, so skip it. Otherwise the firmware will be rejected due to non-matching CRCs.

firmware: Sigma: Prevent out of bounds memory access 2011-12-09T16:52:38+00:00 Lars-Peter Clausen lars@metafoo.de 2011-11-28T08:44:14+00:00 f18cc6ba85619dfee8ed4a9564ae8c0fcb874cbe commit 4f718a29fe4908c2cea782f751e9805319684e2b upstream. The SigmaDSP firmware loader currently does not perform enough boundary size checks when processing the firmware. As a result it is possible that a malformed firmware can cause an out of bounds memory access. This patch adds checks which ensure that both the action header and the payload are completely inside the firmware data boundaries before processing them.
