CVE-2025-46570 vLLM’s Chunk-Based Prefix Caching Vulnerable to Potential Timing Side-Channel

vLLM is an inference and serving engine for large language models LLMs. Prior to version 0.9.0, when a new prompt is processed, if the PageAttention mechanism finds a matching prefix chunk, the prefill process speeds up, which is reflected in the TTFT Time to First Token. These timing differences...

CVE-2024-23218

A timing side-channel issue was addressed with improvements to constant-time computation in cryptographic functions. This issue is fixed in iOS 16.7.6 and iPadOS 16.7.6, iOS 17.3 and iPadOS 17.3, macOS Monterey 12.7.4, macOS Sonoma 14.3, macOS Ventura 13.6.5, tvOS 17.3, watchOS 10.3. An attacker...

CVE-2024-37880

The Kyber reference implementation before 9b8d306, when compiled by LLVM Clang through 18.x with some common optimization options, has a timing side channel that allows attackers to recover an ML-KEM 512 secret key in minutes. This occurs because polyfrommsg in poly.c does not prevent Clang from...

CVE-2023-26556

io.finnet tss-lib before 2.0.0 can leak a secret key via a timing side-channel attack because it relies on the scalar-multiplication implementation in Go crypto/elliptic, which is not constant time there is an if statement in a loop. One leak is in ecdsa/keygen/round2.go. bnb-chain/tss-lib and...

CVE-2023-26557

io.finnet tss-lib before 2.0.0 can leak the lambda value of a private key via a timing side-channel attack because it relies on Go big.Int, which is not constant time for Cmp, modular exponentiation, or modular inverse. An example leak is in crypto/paillier/paillier.go. bnb-chain/tss-lib and...

CVE-2023-33850

IBM GSKit-Crypto could allow a remote attacker to obtain sensitive information, caused by a timing-based side channel in the RSA Decryption implementation. By sending an overly large number of trial messages for decryption, an attacker could exploit this vulnerability to obtain sensitive...

CVE-2022-25332

The AES implementation in the Texas Instruments OMAP L138 secure variants, present in mask ROM, suffers from a timing side channel which can be exploited by an adversary with non-secure supervisor privileges by managing cache contents and collecting timing information for different ciphertext...
