An out‑of‑bounds write flaw exists. The error can lead to fatal memory corruption and cause unexpected system termination. The weakness is a classic out‑of‑bounds write, which can compromise system availability by crashing the OS when triggered by a malicious application.

Apple macOS, including macOS Sequoia versions earlier than 15.8 and macOS Tahoe versions earlier than 26.7.

Based on the description, the likely attack vector is local exploitation: an attacker can run a malicious app or exploit a vulnerable component to trigger the out‑of‑bounds write and crash the system. The CVSS score is 5.5, indicating medium‑severity denial‑of‑service risk. The EPSS score is <1%, implying a low probability of exploitation, and the vulnerability is not listed in the CISA KEV catalog.
