Official Description
Potential read out of bounds case with wolfSSHd on Windows while handling a terminal resize request. An authenticated user could trigger the out of bounds read after establishing a connection which would leak the adjacent stack memory to the pseudo-console output.
Technical Analysis
CVE-2026-0930 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
