Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
CWE-119	The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

Attack-Flow Graph

Executive Summary

This vulnerability involves Safari and related Apple operating systems improperly handling memory when processing maliciously crafted web content. This flaw can cause Safari to crash unexpectedly.

Impact Analysis

If exploited, this vulnerability can cause Safari or affected Apple devices to crash unexpectedly when processing certain malicious web content, potentially disrupting your browsing experience.

Compliance Impact

The vulnerability causes an unexpected Safari crash when processing maliciously crafted web content, which impacts availability but does not affect confidentiality or integrity.

Since the issue does not lead to data disclosure or modification, it is unlikely to directly impact compliance with standards like GDPR or HIPAA that focus on protecting personal data confidentiality and integrity.

However, the denial of service caused by the crash could affect system availability, which may be a consideration under some regulatory frameworks.
