CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
10962 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2023-01-13 00:30 – Updated: 2023-01-13 00:30A Use After Free vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). In a Non Stop Routing (NSR) scenario, an unexpected kernel restart might be observed if "bgp auto-discovery" is enabled and if there is a BGP neighbor flap of auto-discovery sessions for any reason. This is a race condition which is outside of an attackers direct control and it depends on system internal timing whether this issue occurs. This issue affects Juniper Networks Junos OS Evolved: 21.3 versions prior to 21.3R3-EVO; 21.4 versions prior to 21.4R2-EVO; 22.1 versions prior to 22.1R2-EVO; 22.2 versions prior to 22.2R1-S1-EVO, 22.2R2-EVO.

Mitigation
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
Strategy: Attack Surface Reduction
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.
No CAPEC attack patterns related to this CWE.
