macOS Tahoe 26.2 Security Update

What macOS Tahoe 26.2 Fixes

macOS Tahoe 26.2, released December 12, 2025, fixes 59 vulnerabilities in 35 parts of the system, according to Apple's security advisory.

Apple says 2 of these flaws — CVE-2025-43529, CVE-2025-14174 — may already have been exploited. That makes macOS Tahoe 26.2 an update to install now rather than at the weekend.

It has since been superseded: the newest security release for macOS Tahoe is macOS Tahoe 26.7.2, from October 26, 2026, which includes these fixes.

Grouped by us from the impact Apple gives for each fix; the impact lines below are Apple's own.

Exploited Before the Fix

Apple flags a fix as possibly exploited when it has a credible report that the flaw was used against real people before the patch. These are the reason to update today.

• WebKit Exploited

  Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 26. CVE-2025-14174 was also issued in response to this report.

  A use-after-free issue was addressed with improved memory management.
