CVE-2026-49413

The Linuxulator determined whether a binary was set-user-ID or set-group-ID by checking the PSUGID process flag. During execve2, this flag is not yet set at the point where the auxiliary vector is constructed, so ATSECURE was incorrectly set to zero for set-user-ID and set-group-ID executables. A...

CVE-2026-49413

The CVE-2026-49413 issue affects the Linuxulator in FreeBSD, where the runtime determines set-user-ID/set-group-ID status by the P_SUGID flag. During execve, P_SUGID is not yet set when the ELF auxiliary vector is constructed, causing AT_SECURE to be incorrectly set to zero for setuid/setgid exec...
