CVE-2026-49425

The compat32 kevent handler translates a 64-bit kevent struct into a stack- declared 32-bit struct. It did not first zero the stack struct. An unprivileged user may observe a small amount of uninitialized kernel stack data, which may contain sensitive information...

CVE-2026-49425

CVE-2026-49425 is a kernel stack information disclosure in the FreeBSD compat32 subsystem (the 32-bit compatibility layer for 64-bit platforms). The kevent() handler translates a 64-bit kevent struct into a stack-declared 32-bit struct without first zeroing it , allowing an unprivileged local use...
