commit: https://git.buildroot.net/buildroot/commit/?id=9ada4eb2f1c3d67ee49f6f5466738bcd821fc647
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Fixes the following security issue:
- wpa_supplicant P2P provision discovery processing vulnerability (no CVE
yet)
A vulnerability was discovered in how wpa_supplicant processes P2P
(Wi-Fi Direct) provision discovery requests. Under a corner case
condition, an invalid Provision Discovery Request frame could end up
reaching a state where the oldest peer entry needs to be removed. With
a suitably constructed invalid frame, this could result in use
(read+write) of freed memory. This can result in an attacker within
radio range of the device running P2P discovery being able to cause
unexpected behavior, including termination of the wpa_supplicant process
and potentially code execution.
For more details, see the advisory:
