The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel denial-of-service issue. A local user may be able to crash or destabilize an affected system by triggering flawed signal-handling behavior. The sources do not show remote compromise, data theft, privilege escalation, or active exploitation.

Executive priority

Treat this as a maintenance-priority kernel update, not an emergency remote-compromise event. Escalate priority for multi-user infrastructure where a local denial of service could affect business operations or availability commitments.

Technical view

CVE-2018-10124 affects Linux kernel kill_something_info in kernel/signal.c before 4.13 under an unspecified architecture and compiler combination. The issue involves handling an INT_MIN argument and may allow a local user to cause denial of service.

Likely exposure

Exposure is most relevant for Linux systems running kernels before 4.13 or vendor-maintained backports referenced by Ubuntu and Debian advisories. Risk is higher on shared servers, developer hosts, and systems allowing untrusted local users.

Exploitation context

The public description identifies local-user denial of service only. The source bundle marks KEV as false and provides no evidence of active exploitation, public weaponization, remote attack, or privilege escalation.

Researcher notes

Evidence is incomplete: CVSS, CWE, exact architecture/compiler conditions, and affected distro package ranges are not included in the bundle. The upstream commit and Ubuntu/Debian advisories indicate a real kernel fix path, but validation should rely on vendor package metadata.

Mitigation direction

  • Check Ubuntu, Debian, and Linux vendor advisories for fixed kernel packages.
  • Apply supported kernel updates or vendor backports during the next maintenance window.
  • Prioritize shared hosts and systems with untrusted local users.
  • Retire or isolate unsupported kernels that cannot receive vendor fixes.

Validation and detection

  • Inventory Linux kernel versions across servers, workstations, and appliances.
  • Compare versions against kernel 4.13 and relevant distro advisory fixed packages.
  • Confirm vendor kernel packages include the upstream fix or a documented backport.
  • Review shared systems for untrusted local shell, container, or workload access.
