AI-suggested
A patch is available and included in Linux kernel versions 7.0.0 and later. Users should upgrade to these fixed versions to remediate the vulnerability. The vendor advisory confirms the availability of fixes in multiple 7.0.0 kernel releases. No additional mitigation is required beyond applying the official kernel updates.
Description
CVE-2026-64467 is a vulnerability in the Linux kernel's rust_binder component where the offsets array cleanup uses an incorrect stride type on 32-bit kernels. This causes reference count underflow due to over-decrementing, potentially corrupting binder's reference accounting. The issue is fixed by changing the stride to u64 and properly reading each entry. The vulnerability affects multiple Linux kernel versions prior to 7.0.0 and has a high severity score of 8.8.
