CVE-2026-107446

Status: Awaiting AnalysisMedium (6.8)—

containerd overlaybd through 1.0.18 has a do_load_index (LSMT index loading) integer overflow (and resultant out-of-bounds heap access) for index_bytes, if an untrusted overlaybd blob from a registry is used in a scenario with multiple overlaybd-backed containers.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H
Base score: 6.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.41%
