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.
