CVE-2026-32284 (GCVE-0-2026-32284)

Vulnerability from cvelistv5 – Published: 2026-03-26 19:40 – Updated: 2026-03-30 14:55
VLAI?
Title
Denial of service in github.com/shamaton/msgpack
Summary
The msgpack decoder fails to properly validate the input buffer length when processing truncated fixext data (format codes 0xd4-0xd8). This can lead to an out-of-bounds read and a runtime panic, allowing a denial of service attack.
Severity ?
