CVE-2025-71116

Severity CVSS v4.0:
Pending analysis
Type:
CWE-125 Out-of-bounds Read
Publication date:
14/01/2026
Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> libceph: make decode_pool() more resilient against corrupted osdmaps<br /> <br /> If the osdmap is (maliciously) corrupted such that the encoded length<br /> of ceph_pg_pool envelope is less than what is expected for a particular<br /> encoding version, out-of-bounds reads may ensue because the only bounds<br /> check that is there is based on that length value.<br /> <br /> This patch adds explicit bounds checks for each field that is decoded<br /> or skipped.
