Vulnerability from cvelistv5
Published
2026-05-08 14:21
Modified
2026-10-19 19:16
Severity ?
9.1 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: libceph: prevent potential out-of-bounds reads in process_message_header() If the message frame is (maliciously) corrupted in a way that the length of the control segment ends up being less than the size of the message header or a different frame is made to look like a message frame, out-of-bounds reads may ensue in process_message_header(). Perform an explicit bounds check before decoding the message header.

No race or attacker-uncontrolled timing condition is required.\\nPR:N - The vulnerable read can occur during CEPH_CON_S_V2_HELLO or CEPH_CON_S_V2_AUTH before credentials are verified, so the network peer does not need authenticated privileges.\\nUI:N - In a reasonable deployment with an already configured or reconnecting Ceph client, a malicious or spoofed Ceph peer can send the frame without further victim action.\\nS:U - The impact is within the kernel/libceph client security scope and does not cross a VM, IOMMU, or other separate security authority boundary.\\nC:H - The flaw is a slab out-of-bounds read of attacker-triggered kernel memory beyond a too-small control buffer. Following the required guidance, an out-of-bounds read that is not strictly limited to only a few bytes is scored High for confidentiality.\\nI:N - The defect is an out-of-bounds read, and the investigated path does not provide an out-of-bounds write, memory corruption, or authenticated message dispatch that would directly modify data.\\nA:H - The malformed network frame deterministically triggers a KASAN-detected slab out-of-bounds access in the ceph-msgr workqueue and can fault/disrupt the Ceph client connection.
