CVE-2026-55588

ORAS OCI Registry As Storage is a CLI and library for managing artifacts in OCI registries. In ORAS CLI versions up to and including 1.3.2, the recursive referrer traversal does not track visited descriptors, so a malicious OCI registry that returns a cyclic referrer graph causes unbounded...

PT-2026-81849

Name of the Vulnerable Software and Affected Versions ORAS CLI versions prior to 1.3.3 Description Recursive referrer traversal fails to track visited descriptors, allowing a malicious OCI registry to return a cyclic referrer graph. This leads to unbounded recursion and memory growth, resulting i...

CVE-2026-59645

A flaw was found in Bouncy Castle for Java. A remote attacker could exploit this vulnerability by providing a specially crafted self-referential IEEE 1609.2 schema to the OER Octet Encoding Rules parser. This can cause the parser to recurse without a depth limit, leading to resource exhaustion an...

GHSA-CV2G-M8RR-888C Duplicate Advisory: Natural Language Toolkit (NLTK) has unbounded recursion in JSONTaggedDecoder.decode_obj() may cause DoS

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-rf74-v2fm-23pw. This link is maintained to preserve external references. Original Description NLTK versions before 3.9.4 contain an unbounded recursion vulnerability in JSONTaggedDecoder.decodeobj that allows...

CVE-2026-66393

NLTK versions before 3.9.4 contain an unbounded recursion vulnerability in JSONTaggedDecoder.decodeobj that allows attackers to cause denial of service by supplying deeply nested JSON structures.

Linux Distros Unpatched Vulnerability : CVE-2026-66393

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - NLTK versions before 3.9.4 contain an unbounded recursion vulnerability in JSONTaggedDecoder.decodeobj that allows attackers to cause denial of service by...

CVE-2026-53531 ratex-parser has unbounded parser recursion that leads to stack overflow (process abort)

RaTeX is a KaTeX-compatible math rendering engine written in Rust. Prior to version 0.1.11, RaTeX’s recursive-descent parser recurses one or more native stack frame per nesting level at , \left, \sqrt, ^, etc, with no maximum depth limit. A short, 10 KB input of nested groups overflows the 8 MB...

CVE-2026-74576

A flaw was found in the Linux kernel's memory management. This vulnerability allows for unbounded recursion in the slab free path, a process where the kernel manages and releases small blocks of memory. When certain kernel memory allocation caches kmalloc caches form a cycle during internal data...

SUSE CVE-2026-72194

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: add depth limit to indxfindbuffer to prevent stack overflow indxfindbuffer recursively descends the B+ tree index with no depth limit. A crafted NTFS image with circular index node references causes unbounded recursion,...

php: PHP: Denial of Service via circular symbolic links in phar archives

A flaw was found in PHP. When processing a specially crafted PHP Archive phar file containing circular symbolic links, the PHP process can enter an uncontrolled loop. This unbounded recursion exhausts the program's memory stack, causing the PHP application to crash. This vulnerability could allow...
