CVE-2026-28815: A remote attacker can supply a short X-Wing HPKE encapsulated key and trigger an out-of-bounds read in the C decapsulation path, potentially causing a crash or memory disclosure depending on runtime protections. in Apple macOS
A remote attacker can supply a short X-Wing HPKE encapsulated key and trigger an out-of-bounds read in the C decapsulation path, potentially causing a crash or memory disclosure depending on runtime protections. This issue is fixed in swift-crypto version 4.3.1.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read triggered by a specially crafted short X-Wing HPKE encapsulated key during the C decapsulation process in Apple macOS's swift-crypto library version 4.0.0. The flaw can lead to application crashes or memory disclosure depending on the system's runtime protections. The problem is addressed in swift-crypto version 4.3.1.
Potential Impact
An attacker remotely supplying a malformed encapsulated key can cause the affected software to read memory out-of-bounds, which may result in a crash or potentially disclose sensitive memory contents. The actual impact depends on runtime memory protection mechanisms in place. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade to swift-crypto version 4.3.1 or later, where this vulnerability is fixed. Since this is a software library issue, applying the official patch is the recommended remediation. No other mitigations or temporary fixes are indicated.
