Hello Cypress people,

Can we please get updated firmware for
brcm/brcmfmac4356-pcie.bin and brcm/brcmfmac4356-sdio.bin
fixing CVE-2019-15126 as well as for any other affected
models (the 4356 is explicitly named in the CVE description) ?

The current Cypress firmware files in linux-firmware are
quite old, e.g. for brcm/brcmfmac4356-pcie.bin linux-firmware has:
version 7.35.180.176 dated 2017-10-23, way before the CVE

Where as https://community.cypress.com/docs/DOC-19000 /
cypress-fmac-v4.14.77-2020_0115.zip has:
version 7.35.180.197 which presumably contains a fix (no changelog)

Regards,

Hans
