Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2026-20654)
The vulnerability allows a local application to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in Kernel. A local application can cause unexpected system termination.
2) Buffer overflow (CVE-ID: CVE-2026-20635)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary error in WebKit when processing HTML content. A remote attacker can trick the victim into visiting a specially crafted website and crash the browser.
3) Information disclosure (CVE-ID: CVE-2026-20641)
The vulnerability allows a local application to gain access to sensitive information.
The vulnerability exists due to excessive data output by StoreKit. A local application can identify what other apps a user has installed.
4) Permissions, privileges, and access controls (CVE-ID: CVE-2026-20628)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to improperly imposed security restrictions in Sandbox. A local application can break out of its sandbox.
5) Resource exhaustion (CVE-ID: CVE-2025-59375)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger large dynamic memory allocations via a small document and perform a denial of service (DoS) attack.
6) Man-in-the-Middle (MitM) attack (CVE-ID: CVE-2026-20671)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to a logic issue in the OS kernel. A remote attacker on the local network can intercept network traffic.
7) Out-of-bounds read (CVE-ID: CVE-2026-20634)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when parsing SGI images within the ImageIO framework. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
8) Input validation error (CVE-ID: CVE-2026-20650)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in Bluetooth. A remote attacker in a privileged network position can send specially crafted Bluetooth packets to the system and perform a denial of service (DoS) attack.
9) Integer overflow (CVE-ID: CVE-2026-20675)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow when parsing SGI files. A remote attacker can trick the victim into opening a specially crafted file, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Information disclosure (CVE-ID: CVE-2026-20649)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to excessive data output by the Game Center. A local user can view sensitive user information.
11) Buffer overflow (CVE-ID: CVE-2026-20700)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in dyld. A local user can trigger memory corruption and execute arbitrary code on the target system.
Note, the vulnerability is being actively exploited in the wild in conjunction with vulnerabilities #VU119833 (CVE-2025-14174) and #VU119902 (CVE-2025-43529).
12) Use-after-free (CVE-ID: CVE-2025-43529)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content. A remote attacker can trick the victim into visiting a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.
Note, the vulnerability is being actively exploited in the wild.
13) Out-of-bounds write (CVE-ID: CVE-2025-14174)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error in ANGLE. A remote attacker can trick the victim into visiting a specially crafted website, trigger an out-of-bounds write and execute arbitrary code on the target system.
Note, the vulnerability is being actively exploited in the wild.
14) State issues (CVE-ID: CVE-2026-20617)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a state management issue in CoreServices. A local application can gain root privileges.
15) Memory corruption (CVE-ID: CVE-2026-20609)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in CoreMedia. A remote attacker can trick the victim into opening a specially crafted file and perform a denial-of-service or potentially disclose memory contents.
16) Out-of-bounds write (CVE-ID: CVE-2026-20611)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when decoding audio APAC frames. A remote attacker can create a specially crafted audio file, trick the victim into opening it using the affected software, trigger an out-of-bounds write and execute arbitrary code on the target system.
17) Use after free (CVE-ID: CVE-2026-20637)
The vulnerability allows a local application to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in AppleKeyStore. A local application can cause unexpected system termination.
