CVE-2026-59879 (GCVE-0-2026-59879)

Vulnerability from cvelistv5 – Published: 2026-07-08 15:47 – Updated: 2026-07-08 19:41

Title

Immutable.js `List` 32-bit trie overflow → unrecoverable DoS

Summary

Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, List#set, List#setSize, List#setIn, List#updateIn, and the functional set, setIn, and updateIn mishandle an index or size in the range 2 ** 30 to 2 ** 31 in setListBounds in src/List.js, causing an empty List to enter an uncatchable infinite loop, a populated List to allocate without bound until process abort, or setSize to silently wrap large values. This issue is fixed in versions 4.3.9 and 5.1.8.

Severity

8.7 (High)

Vulnerability from csaf_redhat - Published: 2026-09-17 20:28 - Updated: 2026-09-25 14:33

Summary

Red Hat Security Advisory: General availability of the satellite/iop-host-inventory-frontend-rhel9 container image

Severity

Important

Scope

8 vulnerabilities in this advisory, including CVE-2026-59879.

CVE-2026-59879

A flaw was found in Immutable.js, a library providing persistent immutable data structures. This vulnerability occurs when specific List operations, such as List#set or List#setSize, are provided with an index or size value within a particular large range. An attacker could exploit this by providing specially crafted input, leading to an uncatchable infinite loop or unbounded memory allocation, ultimately causing a Denial of Service (DoS) for applications using the library.
