CVE-2024-41075: cachefiles: add consistency check for copen/cread

In the Linux kernel, the following vulnerability has been resolved: cachefiles: add consistency check for copen/cread This prevents malicious processes from completing random copen/cread requests and crashing the system. Added checks are listed below: * Generic, copen can only complete open requests, and cread can only complete read requests. * For copen, ondemand_id must not be 0, because this indicates that the request has not been read by the daemon. * For cread, the object corresponding to fd and req should be the same.

Security readout for executives and security teams

Plain-English summary

A locally authenticated malicious process may abuse Linux CacheFiles request handling and crash the system. The flaw received a 7.8 CVSS score. Systems allowing untrusted local users or workloads deserve prompt review, especially where CacheFiles functionality is active.

Executive priority

Treat as a high-priority local kernel issue, not an internet-wide emergency. Accelerate remediation for shared hosts, multi-tenant infrastructure, and systems where local compromise could cause material outages. Standard managed endpoints should follow expedited kernel patching after exposure confirmation.

Technical view

CacheFiles lacked consistency checks when completing copen and cread requests. The fix verifies request type, rejects a zero ondemand_id for copen, and ensures cread file descriptors and requests reference the same object. This prevents arbitrary request completion from reaching unsafe state and crashing the kernel.

Likely exposure

Exposure requires an affected Linux kernel and local low-privilege access. Risk is most relevant where CacheFiles copen/cread paths are available. The supplied version data is ambiguous, so confirm exposure against the running distribution's advisory and backport status rather than relying solely on upstream version numbers.

Exploitation context

The supplied record does not list this CVE in KEV and provides no cited evidence of active exploitation. It describes a malicious local process causing a system crash; remote, unauthenticated exploitation is not supported by the provided evidence.

Researcher notes

The record identifies missing semantic validation across CacheFiles copen/cread completions. Available evidence supports a local crash scenario, while the CVSS vector claims high confidentiality, integrity, and availability impacts without explaining those outcomes. Do not infer privilege escalation or data disclosure without additional evidence.

Mitigation direction

  • Update to a vendor-supported kernel containing the relevant upstream fix or distribution backport.
  • Prioritize multi-user and multi-tenant systems where untrusted processes have local access.
  • Check Linux distribution guidance for exact affected packages and reboot requirements.
  • Restrict unnecessary local access while patching is pending.

Validation and detection

  • Record the running kernel and installed kernel package versions.
  • Compare package versions with the applicable distribution security advisory.
  • Confirm whether CacheFiles functionality is configured or operational on each system.
  • Verify the installed kernel contains the relevant upstream fix or documented backport.
  • After updating, confirm systems booted into the corrected kernel.
