CVE-2026-49413

Flaw in Linuxulator execution of setugid binaries

The Linuxulator determined whether a binary was set-user-ID or set-group-ID by checking the P_SUGID process flag.  During execve(2), this flag is not yet set at the point where the auxiliary vector is constructed, so AT_SECURE was incorrectly set to zero for set-user-ID and set-group-ID executables.

An unprivileged local user can inject a shared library via LD_PRELOAD into a set-user-ID or set-group-ID Linux binary, gaining the privileges of that binary.
