CVE-2025-15382 wolfSSL CVE debrief

CVE-2025-15382 is a medium-severity heap buffer over-read vulnerability in wolfSSH's wolfSSH_CleanPath() function. An authenticated remote attacker can trigger the issue via crafted SCP path input containing '/./' sequences, resulting in a heap over read by 1 byte. Defenders responsible for wolfSSH installations, especially those exposed to remote authenticated access, should assess their exposure and prioritize verification and updates. This vulnerability can be exploited by providing crafted SCP path input, and defenders should review and restrict access to SCP functionality to limit the attack surface.
