CVE-2026-20793 (GCVE-0-2026-20793)

Vulnerability from cvelistv5 – Published: 2026-05-12 16:34 – Updated: 2026-05-12 17:17

Summary
Unchecked return value for some Intel(R) QAT software drivers for Windows before version 1.13 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Title
Junos OS: SRX Series: If a specific request is processed by the DNS subsystem flowd will crash
Summary
An Unchecked Return Value vulnerability in the DNS module of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). If an SRX Series device configured for DNS processing, receives a specifically formatted DNS request flowd will crash and restart, which causes a service interruption until the process has recovered. This issue affects Junos OS on SRX Series: * 23.4 versions before 23.4R2-S5, * 24.2 versions before 24.2R2-S1, * 24.4 versions before 24.4R2. This issue does not affect Junos OS versions before 23.4R1.

Mitigation ID: MIT-53

Phase: Implementation

Description:

  • Check the results of all functions that return a value and verify that the value is expected.
Mitigation ID: MIT-56

Phase: Implementation

Description:

  • For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation

Phase: Implementation

Description:

  • Ensure that you account for all possible return values from the function.
Mitigation

Phase: Implementation

Description:

  • When designing a function, make sure you return a value or throw an exception in case of an error.
