vm2 代码注入漏洞

vm2 is a high-level virtual machine/sandbox developed by Czech developer Patrik Simek. It runs untrusted code using Node.js built-in modules listed in the allowlist. Versions of vm2 prior to 3.11.0 had a code injection vulnerability, which stemmed from a sandbox escape vulnerability. This...

net-imap vulnerable to denial of service via high iteration count for `SCRAM-*` authentication

Summary When authenticating a connection with SCRAM-SHA1 or SCRAM-SHA256, a hostile server can perform a computational denial-of-service attack on the client process by sending a big iteration count value. Details A hostile IMAP server can send an arbitrarily large PBKDF2 iteration count in the...

PT-2026-36848

Name of the Vulnerable Software and Affected Versions vm2 versions prior to 3.11.0 Description vm2 is an open source sandbox for Node.js. A sandbox breakout occurs through the inspect function, allowing attackers to write code that escapes the sandbox environment and executes arbitrary commands o...

CVE-2026-42402 Apache Neethi: Policy Normalization Unbounded Resource Allocation DoS

Apache Neethi is vulnerable to a Denial of Service attack through algorithmic complexity in policy normalization. Specially crafted WS-Policy documents can trigger an exponential Cartesian cross-product expansion during the normalization process, causing unbounded memory allocation that exhausts...

CVE-2026-31593

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine virtualization module. When Secure Nested Paging SNP is enabled, an attempt to update the state of an already running and encrypted virtual machine can cause the host system to crash. This vulnerability leads to a Denial of...

CVE-2026-31591

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. This vulnerability allows a local user in userspace to manipulate or run a virtual CPU vCPU while its state is being synchronized during the Secure Nested Paging SNP launch process. This improper synchronization ca...

CVE-2026-31588

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. This vulnerability, a use-after-free, occurs when KVM processes Memory-mapped I/O MMIO writes that span across different memory pages, and an internal temporary variable is used. A malicious guest operating system ...

CVE-2026-31558

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker could potentially trigger an out-of-bounds memory access by providing a negative 'cpuid' parameter to the 'kvmgetvcpubycpuid' function. This could lead to system instability or potentially other...

CVE-2026-31592

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Protect all of sevmemencregisterregion with kvm-lock Take and hold kvm-lock for before checking sevguest in sevmemencregisterregion, as sevguest isn't stable unless kvm-lock is held or KVM can guarantee KVMSEVINIT2 has...
