ext4: xattr: fix null pointer deref in ext4_raw_inode()

03 Exploitation and scoring

Exploitation

Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.

SSVC decision

ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

0.19% probability of exploitation activity in the next 30 days.

EPSS percentile

Ranks above 8.4% of scored records. A rank, not a probability.

NVD base score

The NVD has published no score for this record

NVD CVSS vector

No NVD score to derive

NVD analysis status

Deferred. NVD last modified this record on 2026-07-14.

Red Hat severity
