A race condition in Apple operating systems was discovered in which concurrent processes can corrupt internal state handling. If an application triggers this flaw it may cause the entire system to crash unexpectedly, potentially disrupting user data and availability. The weakness follows the definition of a race condition flaw and is consistent with the commonly cataloged CWE-362.

Apple iOS and iPadOS systems prior to version 26.5.2, and macOS Tahoe prior to version 26.5.2, are impacted. The exact affected releases are those running older versions than the fixed 26.5.2 update. No additional versions or sub‑products are listed.

The CVE entry has a CVSS score of 4.7 and no EPSS value, and the vulnerability is not listed in CISA's KEV catalog. Because the weakness involves application‑initiated race conditions, the likely attack vector is confined to apps running with sufficient privileges. No further exploit conditions or remote vectors are described, so the risk is considered limited to software with the race condition flaw until a patch is applied.
