CVE-2026-64072

Status: AnalyzedMedium (5.5)—

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

nvme: fix bio leak on mapping failure

The local bio is always NULL, so we'd leak the bio if the integrity mapping failed. Just get it directly from the request.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
