CVE-2022-32293Known exploitation

Code execution via WISPR object double free

Published Aug 3, 2022 · Updated Aug 3, 2024

Use-after-free in ConnMan 1.41 and earlier allows man-in-the-middle attackers to crash the service or execute code via a WISPR HTTP reply. The wispr_portal_web_result method frees wp_object without first verifying that the object still exists, permitting a second free during WISPR result handling. An unauthenticated attacker must control the network path for a WISPR query; successful exploitation runs code in the ConnMan process or crashes it.
