CVE-2026-66393 NLTK before 3.9.4 Denial of Service via JSONTaggedDecoder

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. Attackers can craft JSON payloads exceeding the recursion limit to trigger an unhandled RecursionErro...

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...

Elasticsearch 5.x < 8.19.19 / 9.3.x < 9.3.8 / 9.4.x < 9.4.4 DoS (ESA-2026-75)

The version of Elasticsearch installed on the remote host is 5.x prior to 8.19.19, or 9.3.x prior to 9.3.8, or 9.4.x prior to 9.4.4. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-75 advisory. - A flaw in Elasticsearch allows an authenticated user with the privileges...

Elasticsearch 8.19.x < 8.19.20 / 9.0.x < 9.4.5 DoS (ESA-2026-81)

The version of Elasticsearch installed on the remote host is 8.19.x prior to 8.19.20, or 9.0.x prior to 9.4.5. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-81 advisory. - Elasticsearch does not apply its configurable input length restriction to a user-supplied patte...

CVE-2026-74382

A flaw was found in the Linux kernel's clsbpf component, which handles traffic control filtering. A local attacker could exploit this vulnerability by triggering a specific sequence of failures during an offload rollback operation. This leads to an unbounded recursion, causing a stack overflow an...
