CVE-2026-112481

Published Oct 26, 2026 CVSS 3.1 · 6.8 Medium EPSS < 1% KEV · Not listed
Description
An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2. An attacker on the local network may be able to cause unexpected process termination or disclose process memory.

Analysis

AI-generated

Technical impact

The vulnerability is an out‑of‑bounds read in macOS, indexed by CWE‑125. The flaw occurs when the system does not perform proper bounds checking, allowing a developer to read memory past the intended buffer. An attacker that can reach the target via the local network can trigger the bug and either cause a process to terminate unexpectedly or read portions of process memory that should be inaccessible, potentially leaking sensitive information.

Affected Systems

Apple macOS environments are affected. The issue has been addressed in macOS Golden Gate 27.2, macOS Sequoia 15.8.2, and macOS Tahoe 26.7.2; systems running earlier releases remain vulnerable.

Risk and Exploitability

The CVSS score of 6.8 indicates a moderate severity. The EPSS score is listed as < 1%, suggesting a low probability of exploitation. The vulnerability is not present in the CISA KEV catalog. Attackers need local network access to trigger the bug, which is sufficient to cause process crashes or accidental leakage of memory. The risk is moderate to high for machines exposed to that network, but the overall likelihood remains low given the limited exploitation window and the need for local access.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade macOS to the latest patched release (macOS Golden Gate 27.2, Sequoia 15.8.2, or Tahoe 26.7.2).
  • If an upgrade is not immediately possible, isolate the affected machines from untrusted local network traffic to mitigate the local‑network attack vector.
  • Monitor for unexpected process terminations or suspicious memory disclosures, and investigate any related abnormal behavior promptly.
