Common Weakness Enumeration

CWE-416

Allowed

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

10960 vulnerabilities reference this CWE, most recent first.

Foxit PDF Reader Doc Object Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. 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 handling of Doc objects. 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-20225.

VLAI
Details

A Use After Free vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated, network-based attacker to cause a Denial of Service (DoS).On all Junos OS and Junos Evolved platforms, if a routing-instance deactivation is triggered, and at the same time a specific SNMP request is received, a segmentation fault occurs which causes rpd to crash and restart.

This issue affects:

Junos OS:

  • All versions before 21.2R3-S8, 
  • 21.4 versions before 21.4R3-S5,
  • 22.2 versions before 22.2R3-S3,
  • 22.3 versions before 22.3R3-S2,
  • 22.4 versions before 22.4R3,
  • 23.2 versions before 23.2R2.

Junos OS Evolved:

  • All versions before 21.2R3-S8-EVO,
  • 21.4-EVO versions before 21.4R3-S5-EVO,
  • 22.2-EVO versions before 22.2R3-S3-EVO, 
  • 22.3-EVO versions before 22.3R3-S2-EVO,
  • 22.4-EVO versions before 22.4R3-EVO,
  • 23.2-EVO versions before 23.2R2-EVO.

In the Linux kernel, the following vulnerability has been resolved:

RDMA/ucma: Protect mc during concurrent multicast leaves

Partially revert the commit mentioned in the Fixes line to make sure that allocation and erasing multicast struct are locked.

Currently the xarray search can touch a concurrently freeing mc as the xa_for_each() is not surrounded by any lock. Rather than hold the lock for a full scan hold it only for the effected items, which is usually an empty list.

GHSA-2PGJ-5CV2-6XXW

Vulnerability from github – Published: 2025-10-08 12:43 – Updated: 2025-10-08 12:43
VLAI
Summary
FuelVM is vulnerable to heap memory allocation re-use bug
Details

Impact

A memory safety vulnerability was present in the Fuel Virtual Machine (FuelVM), where memory reads could bypass expected access controls. Specifically, when a smart contract performed a mload (or other opcodes which access memory) on memory that had been deallocated using ret, it was still able to access the old memory contents. This occurred because the memory region was not zeroed out or otherwise marked as invalid. As a result, smart contracts could potentially read sensitive data left over from other contracts if the same memory was reallocated, violating isolation guarantees between contracts and enabling unintended data leakage.

All users running affected versions of FuelVM that relied on strict memory isolation between smart contracts were impacted.

Patches

The vulnerability was patched by modifying the FuelVM to ensure that memory deallocated with ret was zeroed out or made inaccessible. The fix was included in FuelVM version v0.60.1 and back-ported to v0.59.3. This patch was released to the Fuel network on Friday, April 18th, 2025.

Workarounds

There were no reliable workarounds that fully mitigated the vulnerability. While developers could manually zero out sensitive memory regions before returning from a function, this approach was error-prone and could not be enforced at the VM level. Upgrading to a patched version remained the recommended course of action.

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.
