CVE-2026-24255: Incomplete Comparison with Missing Factors

NVIDIA Dynamo for Linux contains a vulnerability in the multimodal embedding cache, where an attacker could cause a hash collision by submitting images that share an identical pixel byte sequence but have different dimensions. A successful exploit of this vulnerability might lead to data tamperin...

PYSEC-2026-3480 LMCache: 16-bit multimodal hash collision can poison KV cache entries

A flaw has been found in LMCache up to 0.4.6. This affects the function hexhashtoint16 of the file lmcache/integration/vllm/utils.py of the component KV Cache Handler. Executing a manipulation can lead to use of weak hash. The attack needs to be launched locally. The attack requires a high level ...

PYSEC-2026-3487 mlrun: DataFrame hash collisions can cause dataset artifact path conflicts and silent data corruption

A vulnerability has been found in mlrun up to 1.12.0-rc3. This impacts the function mlrun.utils.helpers.calculatedataframehash of the file mlrun/utils/helpers.py of the component DataFrame Hash Handler. The manipulation leads to use of weak hash. The attack can only be performed from a local...

Incorrect Implementation of Authentication Algorithm

Overview Affected versions of this package are vulnerable to Incorrect Implementation of Authentication Algorithm due to lossy ISO-8859-1 encoding in the digest hash computation. An attacker can log in as a user with a non-Latin-1 password by supplying a collision password that replaces each...

Security Bulletin: Multiple Vulnerabilities in IBM Spectrum Symphony

Summary Multiple vulnerabilities were addressed in IBM Spectrum Symphony 7.3.2 with Fix 603035 Vulnerability Details CVEID:CVE-2026-21717 DESCRIPTION: A flaw in V8's string hashing mechanism causes integer-like strings to be hashed to their numeric value, making hash collisions trivially...

PT-2026-63532

Name of the Vulnerable Software and Affected Versions Eclipse Jetty affected versions not specified Description The Digest authentication server-side component and the DigestAuthentication.apply method in the HTTP client use ISO-8859-1 encoding to process passwords. Because ISO-8859-1 cannot...

GHSA-XVCM-6775-5M9R Immutable: Hash-collision algorithmic complexity denial of service in Immutable.Map/Set

Summary Immutable.Map and Immutable.Set keep keys that share the same 32-bit hash in a collision bucket that is scanned linearly. The string hash is public and deterministic, so an attacker who controls the keys inserted into a Map can craft many keys that all collide, degrading insertion and...

PT-2026-59260

A vulnerability in the DocugamiReader class of the run-llama/llama index repository, up to but excluding version 0.12.41, involves the use of MD5 hashing to generate IDs for document chunks. This approach leads to hash collisions when structurally distinct chunks contain identical text, resulting...

Inefficient Algorithmic Complexity

Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the HashCollisionNode class in Immutable.Map and Immutable.Set. An attacker can cause excessive CPU consumption by supplying a large number of keys with identical 32-bit hashes, leading to degraded...
