CVE-2025-1414Network attack vector

Memory corruption via uninitialized iterator pointer

Published Feb 18, 2025 · Updated Apr 13, 2026

Memory corruption in Firefox before 135.0.1 allows remote attackers to crash the browser through crafted web content. UnsafePreContentIterator::Init can fail while leaving mCurNode uninitialized, and its failure is ignored before iteration over random or poison addresses. No authentication is required, and arbitrary code execution remains a vendor-stated presumption rather than a reproduced outcome.
