CVE-2024-23266: An app may be able to modify protected parts of the file system in Apple macOS
CVE-2024-23266 is a memory corruption vulnerability in the macOS kernel that could allow an app to cause unexpected system termination or write kernel memory. This issue affects multiple macOS versions including Monterey, Ventura, and Sonoma. Apple addressed the vulnerability by improving locking mechanisms in the kernel. The CVSS score is 5. 5, indicating a medium severity level. No known exploits are reported in the wild. The vulnerability is fixed in macOS Monterey 12. 7. 4, macOS Ventura 13. 6.
AI Analysis
Technical Summary
CVE-2024-23266 is a kernel memory corruption vulnerability in Apple macOS that may allow an application to cause unexpected system termination or write to kernel memory. The flaw was addressed by Apple through improved locking in the kernel to prevent this memory corruption. The vulnerability affects macOS Monterey, Ventura, and Sonoma versions prior to the specified patched releases. The CVSS v3.1 base score is 5.5 with vector AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N, indicating local attack vector with low attack complexity, no privileges required, user interaction required, unchanged scope, no confidentiality impact, high integrity impact, and no availability impact. Apple released official patches in macOS Monterey 12.7.4, Ventura 13.6.5, and Sonoma 14.4 to remediate this issue.
Potential Impact
An unprivileged app with local access and user interaction could exploit this vulnerability to write to kernel memory or cause unexpected system termination, potentially impacting system integrity. There is no confidentiality or availability impact reported. No known exploits in the wild have been observed. The vulnerability could allow integrity violations but does not grant elevated privileges or direct code execution.
Mitigation Recommendations
Apple has released official patches for this vulnerability in macOS Monterey 12.7.4, macOS Ventura 13.6.5, and macOS Sonoma 14.4. Users and administrators should apply these updates promptly to remediate the issue. No additional mitigation steps are indicated by Apple beyond applying the official security updates.
