mruby 资源管理错误漏洞

MRuby is a lightweight implementation of the Ruby language, developed by Makesoftwaresafe as open source. Versions of MRuby 3.4.0 and earlier contain a resource management vulnerability. This vulnerability stems from a flaw in the mrbvmexec function in the src/vm.c file within the JMPNOT-to-JMPIF...

Infinite loop

Overview @enclave-vm/core is a Sandbox runtime for secure JavaScript code execution Affected versions of this package are vulnerable to Infinite loop via infinite recursion in the vm module. An attacker can execute arbitrary code outside the intended sandbox by crafting recursive calls that explo...

Sandbox escape via infinite recursion and error objects

Note: The npm package has moved to @enclave-vm/core formerly enclave-vm. All fixed versions and guidance refer to @enclave-vm/core. Summary The existing layers of security in enclave-vm are insufficient: The AST sanitization can be bypassed with dynamic property accesses, the hardening of the err...

CVE-2026-23056

The CVE concerns the Linux kernel uacce driver: the vm_operations_struct.mremap operation is not implemented, and the fix disables mremap by implementing .mremap to return -EPERM. Without this, the default mremap could replay a vma’s vm_private_data (q) to a new vma, causing two munmap triggers t...
