Improper Validation of Unsafe Equivalence in Input in Kata Containers - CVE-2026-77176
Published: August 21, 2026
Vulnerability details
The vulnerability allows a remote user to mount attacker-chosen guest paths or host-provided content at specific in-guest locations, which could disclose sensitive information or compromise data integrity.
The vulnerability exists due to improper validation of unsafe equivalence in genpolicy-generated mount policy handling when processing CreateContainer requests. A remote user can craft a specially crafted CreateContainer request to mount attacker-chosen guest paths or host-provided content at specific in-guest locations, which could disclose sensitive information or compromise data integrity.
This issue only affects configurations that use genpolicy to protect the guest from the host, such as Confidential Containers; Kata sandboxing is not affected.
