The vulnerability was discovered and disclosed on December 26, 2021, affecting the vec-const project's implementation of vector construction from constant slices (NVD CVE, MITRE CVE).

Technical details

The vulnerability stems from an implementation flaw where the crate attempts to construct a Vec from a pointer to a const slice, which can lead to memory corruption. The severity of this vulnerability is rated as HIGH with a CVSS v3.1 Base Score of 7.5 (Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). The vulnerability is classified as CWE-787 (Out-of-bounds Write) (NVD CVE).

Impact

The vulnerability can result in memory corruption when exploited, potentially leading to system instability or crashes. The high CVSS score particularly reflects the significant impact on system availability, though confidentiality and integrity impacts are not directly indicated (NVD CVE).

Mitigation and workarounds

The vulnerability has been addressed in version 2.0.0 of the vec-const crate. Users are strongly advised to upgrade to this version or later to mitigate the security risk (NVD CVE).
