An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4. An app may be able to disclose kernel memory.
AnalysisAI
macOS versions prior to Sequoia 15.7.5, Sonoma 14.8.5, and Tahoe 26.4 contain an out-of-bounds read vulnerability that allows local applications to access and disclose sensitive kernel memory. An attacker with the ability to run code on an affected system can exploit this memory disclosure to obtain privileged information that may aid in further system compromise. …

RemediationAI
Within 24 hours: Inventory all macOS systems running Sequoia pre-15.7.5, Sonoma pre-14.8.5, or Tahoe pre-26.4; isolate high-risk endpoints from sensitive networks if immediate patching is infeasible. Within 7 days: Apply vendor patches-Sequoia 15.7.5 or later, Sonoma 14.8.5 or later, Tahoe 26.4 or later-to all affected devices via MDM or manual update. …
