Sam, All,

Usually, when there is a patch to hostpad to fix a CVE, we probably need
the same patch against wpa_supplicant, since they both shared the same
source tree...

See for example:

    0c65499c3f package/wpa_supplicant: fix build with CVE-2021-30004 changes
    75496165dc package/hostapd: fix build with CVE-2021-30004 changes
    a8fbe67b9b package/wpa_supplicant: add upstream patch to fix CVE-2021-30004
    d65586f45a package/hostapd: add upstream patch to fix CVE-2021-30004
    2f6a6b8e50 package/wpa_supplicant: ignore CVE-2021-30004 when using openssl
    3d3348fd03 package/hostapd: ignore CVE-2021-30004 when using openssl
    650d907c13 package/wpa_supplicant: fix CVE-2019-16275
    749fbab0bb package/hostapd: fix CVE-2019-16275

Could you look at providing a patch to wpa_supplicant for
CVE-2021-27803, please?

Regards,
Yann E. MORIN.
