Vulnerability from github – Published: 2022-05-24 17:46 – Updated: 2022-05-28 00:00
VLAI
Details

In FreeBSD 13.0-STABLE before n245050, 12.2-STABLE before r369525, 13.0-RC4 before p0, and 12.2-RELEASE before p6, listening socket accept filters implementing the accf_create callback incorrectly freed a process supplied argument string. Additional operations on the socket can lead to a double free or use after free.

GHSA-G943-C7GQ-998H

Vulnerability from github – Published: 2025-07-10 09:32 – Updated: 2025-12-19 18:31
VLAI
Details

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

bus: fsl-mc: fix double-free on mc_dev

The blamed commit tried to simplify how the deallocations are done but, in the process, introduced a double-free on the mc_dev variable.

In case the MC device is a DPRC, a new mc_bus is allocated and the mc_dev variable is just a reference to one of its fields. In this circumstance, on the error path only the mc_bus should be freed.

This commit introduces back the following checkpatch warning which is a false-positive.

WARNING: kfree(NULL) is safe and this check is probably not required + if (mc_bus) + kfree(mc_bus);

Severity
7.8 (High)

GHSA-G9CV-62XC-FJ2V

Vulnerability from github – Published: 2022-05-24 17:49 – Updated: 2022-05-24 17:49
VLAI
Details

There is a pointer double free vulnerability in some versions of CloudEngine 5800, CloudEngine 6800, CloudEngine 7800 and CloudEngine 12800. When a function is called, the same memory pointer is copied to two functional modules. Attackers can exploit this vulnerability by performing a malicious operation to cause the pointer double free. This may lead to module crash, compromising normal service.

Mitigation
Architecture and Design

Choose a language that provides automatic memory management.

Mitigation
Implementation

Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.

Mitigation
Implementation

Use a static analysis tool to find double free instances.
