WebKit out-of-bounds write leading to code execution (Apple iOS/iPadOS/macOS/Safari)

IdentifiersCVE-2022-32893CWE-787· Out-of-bounds Write

CVE-2022-32893 is an out-of-bounds write vulnerability in Apple WebKit. Apple reports it was addressed via improved bounds checking. Processing maliciously crafted web content can trigger the out-of-bounds write and may lead to arbitrary code execution. Apple stated it is aware of a report that this issue may have been actively exploited in the wild. The issue is fixed in iOS 15.6.1 and iPadOS 15.6.1, macOS Monterey 12.5.1, and Safari 15.6.1.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation may result in arbitrary code execution in the context of the WebKit/Safari content processing, potentially enabling full compromise depending on sandbox escapes and chaining. Apple reported the issue may have been actively exploited.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure to untrusted web content (e.g., restrict browsing to trusted sites, limit use of WebKit-based browsers on at-risk devices) until updates can be deployed. Prioritize patching internet-exposed and high-risk user populations due to reported in-the-wild exploitation.

Remediation

Patch, then assume compromise.

Apply Apple security updates that include the fix: iOS 15.6.1 / iPadOS 15.6.1, macOS Monterey 12.5.1, and Safari 15.6.1 (or later).
