Security readout for executives and security teams
Plain-English summary
CVE-2019-10142 is a local Linux kernel flaw in the Freescale hypervisor manager. A low-privileged local user could trigger incorrect size handling, potentially causing a system crash, memory corruption, or other security impact. This is not described as remotely exploitable in the provided sources.
Executive priority
Treat as a high-priority patching item for affected Linux hosts, especially multi-user or shared systems. Business urgency is lower than a remote unauthenticated issue, but kernel memory corruption and crash potential make delayed remediation risky where local users are not fully trusted.
Technical view
The vulnerable ioctl path incorrectly validates a parameter used in page-size calculations. The CVE maps to memory bounds and integer overflow classes, with CVSS 7.1: local attack, low complexity, low privileges, no user interaction, high confidentiality impact, and high availability impact.
Likely exposure
Exposure appears limited to systems running affected Linux kernel 5.0.x versions before 5.0.17 with the Freescale hypervisor manager implementation present. The bundle does not identify specific Red Hat package names, architectures, or runtime configuration prerequisites beyond the kernel version range.
Exploitation context
The source bundle does not cite active exploitation, public exploit availability, or CISA KEV inclusion. Exploitation requires local low-privileged access. Reported outcomes include crash, memory corruption, or other adverse security effects, but the sources do not provide validated exploitation details.
Researcher notes
Evidence is limited to the CVE description, CVSS vector, CWE mappings, affected kernel range, and Red Hat Bugzilla reference. Do not assume broader versions, remote reachability, confirmed exploit chains, or vendor-specific fixes unless validated through distribution advisories.
Mitigation direction
- Upgrade affected 5.0.x kernels to 5.0.17 or outside the vulnerable range.
- Check Red Hat or distribution guidance for fixed package names and backports.
- Prioritize hosts where untrusted users can obtain local shell access.
- Restrict local account access where practical until patched.
Validation and detection
- Inventory Linux kernel versions and flag 5.0.x releases before 5.0.17.
- Confirm whether affected systems include the Freescale hypervisor manager implementation.
- Check vendor advisories for distribution-specific backported fixes.
- Review local-user exposure on affected hosts.
