MemMorph: Tool Hijacking in LLM Agents Via Memory Poisoning

LLM-driven agents are capable of selecting external tools to complete users' tasks. However, attackers could compromise such process, steering agents toward inappropriate/wrong tools and enabling malicious actions. Most existing attacks primarily manipulate the tool metadata, which is easily...

Reasoning As an Attack Surface: Adaptive Evolutionary CoT Jailbreaks for LLMs

Large Reasoning Models LRMs have demonstrated remarkable capabilities in reasoning and generation tasks and are increasingly deployed in real-world applications. However, their explicit chain-of-thought CoT mechanism introduces new security risks, making them particularly vulnerable to jailbreak...

Integer Overflow or Wraparound

Overview github.com/golang/crypto/ssh is a SSH client and server Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the payload size calculation within the Write process. An attacker can cause the process to enter an infinite loop and exhaust system resources by...

CVE-2026-39834 Invoking infinite loop on large channel writes in golang.org/x/crypto/ssh

When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent truncation...

CVE-2026-39829 Invoking pathological RSA/DSA parameters may cause DoS in golang.org/x/crypto/ssh

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public...

CVE-2026-39834

CVE-2026-39834 concerns a flaw in golang.org/x/crypto/ssh where writing data larger than 4GB in a single Write on an SSH channel triggers an integer overflow in the internal payload size calculation. The overflow causes the write loop to spin indefinitely, sending empty packets and making no prog...

AI Security Research Should Better Incentivize Defense Research

This work examines an imbalance in artificial intelligence AI security research: the field tends to produce more work on attacking AI systems than on defending them. Drawing on related academic papers, we find biased attack-to-defense ratios across subfields, including federated learning, speech...

PT-2026-42713

Name of the Vulnerable Software and Affected Versions The product name cannot be determined affected versions not specified Description An integer overflow occurs during the internal payload size calculation when writing data exceeding 4GB in a single Write call on an SSH channel. This leads to a...

An Empirical Evaluation of LLM-Generated Code Security across Prompting Methods

The growing use of Large Language Models LLMs for automated code generation has enhanced software development efficiency, but often at the cost of security. Generated code frequently overlooks critical concerns, leaving it vulnerable to issues such as weak encryption and improper input validation...
