CVE-2026-65061

Local IPC disclosure via insecure backing-file creation

Published Jul 21, 2026 · Updated Jul 21, 2026

Information disclosure in Yegor Korablev Data::ReqRep::Shared before 0.05 allows local users to read shared IPC payloads. In reqrep.h, both segment variants call open with O_RDWR and O_CREAT mode 0666, omitting O_EXCL and O_NOFOLLOW for attacker-influenced paths. A local account with access to the shared directory can read the resulting world-readable mapping or preplant a file or symlink to redirect its creation.
