When a process calls execve(2) to execute a setuid or setgid image, hwpmc(4) is supposed to detach PMCs owned by unprivileged processes. An inverted check meant that this scenario was not handled properly. An unprivileged local user who has attached PMCs to a process can continue monitoring it after the process executes a setuid or setgid binary, contrary to the intended policy.

An Ubuntu-specific patch to AccountsService before 23.13.9-8ubuntu7 only partially drops privileges before launching language helper scripts. It changes the effective UID/GID to the target user but leaves the real UID as 0 (root). A shell spawned by a helper script inherits ruid=0 and may reset its effective UID to root, enabling local privilege escalation.

sh provides Python process launching. Prior to 2.2.4, the _uid option in sh.py performs an incomplete privilege drop on Linux and Unix-like systems. When sh runs from an elevated process and launches a command with _uid set to an unprivileged user, the child changes its UID but can retain the parent process's supplementary groups because the privilege-drop sequence does not fully establish the tar…

PraisonAI before 4.6.78 contains an unenforced security policy vulnerability in the default Subprocess Sandbox backend where blocked_commands, blocked_paths, blocked_imports, allow_subprocess, and allow_file_write restrictions are completely ignored. Attackers can execute arbitrary subprocess commands, read sensitive files, and perform destructive operations despite explicit security policy config…
