Severity

9.8 (Critical) CVSS_V3 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H CVSS Calculator

Summary

Double-free and use-after-free in SmallVec::grow()

Details

Attempting to call grow on a spilled SmallVec with a value equal to the current capacity causes it to free the existing data. This performs a double free immediately and may lead to use-after-free on subsequent accesses to the SmallVec contents.

An attacker that controls the value passed to grow may exploit this flaw to obtain memory contents or gain remote code execution.
