CWE-416

Use After Free

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

CVE-2018-14305 (GCVE-0-2018-14305)

Vulnerability from cvelistv5 – Published: 2018-07-31 20:00 – Updated: 2024-08-05 09:21

The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-6327.

CVE-2018-14619 (GCVE-0-2018-14619)

Vulnerability from cvelistv5 – Published: 2018-08-30 12:00 – Updated: 2024-08-05 09:29
VLAI
Summary
A flaw was found in the crypto subsystem of the Linux kernel before version kernel-4.15-rc4. The "null skcipher" was being dropped when each af_alg_ctx was freed instead of when the aead_tfm was freed. This can cause the null skcipher to be freed while it is still in use leading to a local user being able to crash the system or possibly escalate privileges.

Mitigation

Phase: Architecture and Design

Strategy: Language Selection

Description:

  • Choose a language that provides automatic memory management.
Mitigation

Phase: Implementation

Strategy: Attack Surface Reduction

Description:

  • When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
