CVE-2024-55884
In the Mullvad VPN client 2024.6 (Desktop), 2024.8 (iOS), and 2024.8-beta1 (Android), the exception-handling alternate stack can be exhausted, leading to heap-based out-of-bounds writes in enable() in exception_logging/unix.rs, aka MLLVD-CR-24-01.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
