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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9854 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2022-02-19 00:01 – Updated: 2022-02-26 00:00This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley MicroStation CONNECT 10.16.0.80. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of JT files. 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-15382.

GHSA-R4G7-RP4J-9CV7
Vulnerability from github – Published: 2024-04-12 18:33 – Updated: 2025-02-06 21:32A Use-After-Free vulnerability in the Layer 2 Address Learning Daemon (l2ald)
of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause l2ald to crash leading to a Denial-of-Service (DoS).
In an EVPN-VXLAN scenario, when
state updates are received and processed by the affected system, the correct order of some processing steps is not ensured, which can lead to an l2ald crash and restart. Whether the crash occurs depends on system internal timing which is outside the attackers control. This issue affects:
Junos OS:
- All versions before 20.4R3-S8,
- 21.2 versions before 21.2R3-S6,
- 21.3 versions before 21.3R3-S5,

- 22.2 versions before 22.2R3-S1,
- 22.3 versions before 22.3R3,,
- 22.4 versions before 22.4R2;
Junos OS Evolved:
