Overview

CVE-2026-46285 is a high-severity vulnerability. It was published on June 8, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

mtd: docg3: fix use-after-free in docg3_release()

In docg3_release(), the docg3 pointer is obtained from

cascade->floors[0]->priv before the loop that calls

doc_release_device() on each floor. doc_release_device() frees the

docg3 struct via kfree(docg3) at line 1881. After the loop,

docg3->cascade->bch dereferences the already-freed pointer.

Fix this by accessing cascade->bch directly, which is equivalent

since docg3->cascade points back to the same cascade struct, and

is already available as a local variable. This also removes the

now-unused docg3 local variable.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
