A buffer overflow arises from inadequate size validation in the system, allowing a flaw that can be triggered by an application to cause the operating system to terminate unexpectedly. The impact is a crash of the entire system, leading to potential loss of availability and interruption of service for any user or process dependent on the operating system. This vulnerability falls under the category of buffer overflow weaknesses that can destabilize system execution flow.

Apple macOS Tahoe versions older than 26.6 are affected. Any installations running these releases without the security update are susceptible.

Because the CVE only documents that an application may trigger the overflow to cause system termination, the specific prerequisites for exploitation are not detailed. The vulnerability is not listed in CISA’s KEV catalog, and the EPSS score is < 1%, indicating a very low exploitation probability at this time. The impact is a denial‑of‑service condition, leading to loss of availability rather than code execution or data disclosure.
