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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9854 vulnerabilities reference this CWE, most recent first.

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

cifs: Fix UAF in cifs_demultiplex_thread()

There is a UAF when xfstests on cifs:

The UAF is because:

mount(pid: 921) cifsd(pid: 923)
cifs_demultiplex_thread
SMB2_negotiate
cifs_send_recv
compound_send_recv
smb_send_rqst
wait_for_response
wait_event_state [1]
standard_receive3
cifs_handle_standard
handle_mid
mid->resp_buf = buf; [2]
dequeue_mid [3]
KILL the process [4]
resp_iov[i].iov_base = buf
free_rsp_buf [5]
is_network_name_deleted [6]
callback
  1. After send request to server, wait the response until mid->mid_state != SUBMITTED;
  2. Receive response from server, and set it to mid;
  3. Set the mid state to RECEIVED;
  4. Kill the process, the mid state already RECEIVED, get 0;
  5. Handle and release the negotiate response;
  6. UAF.

It can be easily reproduce with add some delay in [3] - [6].

Only sync call has the problem since async call's callback is executed in cifsd process.

Add an extra state to mark the mid state to READY before wakeup the waitter, then it can get the resp safely.

Vulnerability from github – Published: 2022-02-19 00:01 – Updated: 2022-02-26 00:00
VLAI
Details

This 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 3DS 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-15381.

GHSA-RJH6-H795-3MRJ

Vulnerability from github – Published: 2023-08-08 12:30 – Updated: 2024-04-04 06:38
VLAI
Details

In the function call related to CAM_REQ_MGR_RELEASE_BUF there is no check if the buffer is being used. So when a function called cam_mem_get_cpu_buf to get the kernel va to use, another thread can call CAM_REQ_MGR_RELEASE_BUF to unmap the kernel va which cause UAF of the kernel address.

Implementation

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.
