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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9811 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2024-04-03 18:30 – Updated: 2024-04-03 18:30Foxit 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-22638.

GHSA-P7RJ-MGWW-3Q4F
Vulnerability from github – Published: 2024-07-14 09:30 – Updated: 2024-08-21 18:31In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Fix UAF in svc_tcp_listen_data_ready()
After the listener svc_sock is freed, and before invoking svc_tcp_accept() for the established child sock, there is a window that the newsock retaining a freed listener svc_sock in sk_user_data which cloning from parent. In the race window, if data is received on the newsock, we will observe use-after-free report in svc_tcp_listen_data_ready().
Reproduce by two tasks:
- while :; do rpc.nfsd 0 ; rpc.nfsd; done
- while :; do echo "" | ncat -4 127.0.0.1 2049 ; done

Fix the UAF by simply doing nothing in svc_tcp_listen_data_ready() if state != TCP_LISTEN, that will avoid dereferencing svsk for all child socket.

GHSA-P7RV-2F34-8MWF
Vulnerability from github – Published: 2025-03-27 18:31 – Updated: 2025-03-27 18:31In the Linux kernel, the following vulnerability has been resolved:
net: nfc: Fix use-after-free in local_cleanup()
Fix a use-after-free that occurs in kfree_skb() called from local_cleanup(). This could happen when killing nfc daemon (e.g. neard) after detaching an nfc device. When detaching an nfc device, local_cleanup() called from nfc_llcp_unregister_device() frees local->rx_pending and decreases local->ref by kref_put() in nfc_llcp_local_put(). In the terminating process, nfc daemon releases all sockets and it leads to decreasing local->ref. After the last release of local->ref, local_cleanup() called from local_release() frees local->rx_pending again, which leads to the bug.
Setting local->rx_pending to NULL in local_cleanup() could prevent use-after-free when local_cleanup() is called twice.
Found by a modified version of syzkaller.
