NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs20-libs-debuginfo package and not the nodejs20-libs-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

In Node.js, the ReadFileUtf8 internal binding leaks memory due to a corrupted pointer in uv_fs_s.file: a UTF-16 path buffer is allocated but subsequently overwritten when the file descriptor is set. This results in an unrecoverable memory leak on every call. Repeated use can cause unbounded memory growth, leading to a denial of service.

Impact:

  • This vulnerability affects APIs relying on ReadFileUtf8 on Node.js release lines: v20 and v22.
