CVE-2026-93257

Status: ReceivedUnscored—

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

block: handle nogenerate/noverify properly in fs-integrity

Check the BIP_CHECK flags before generating or verifying PI information, otherwise this can be incorrectly called for non-PI metadata and cause generation of incorrect metadata and crashed in the verification handler.

The new behavior matches that of the block layer auto-generated metadata.

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

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).
