In Tensorflow before versions 2.2.1 and 2.3.1, if a user passes an invalid argument to `dlpack.to_dlpack` the expected validations will cause variables to bind to `nullptr` while setting a `status` variable to the error condition. However, this `status` argument is not properly checked. Hence, code following these methods will bind references to null pointers. This is undefined behavior and reported as an error if compiling with `-fsanitize=null`. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.

An issue was discovered on Samsung mobile devices with M(6.0) software. The multiwindow_facade API allows attackers to cause a NullPointerException and system halt via an attempted screen touch of a non-existing display. The Samsung ID is SVE-2017-9383 (August 2017).

libyang from v2.0.164 to v2.1.30 was discovered to contain a NULL pointer dereference via the function lys_parse_mem at lys_parse_mem.c.

A NULL Pointer Dereference vulnerability in Cesanta Frozen versions less than 1.7 allows an attacker to induce a crash of the component embedding the library by supplying a maliciously crafted JSON as input.

The login routine of the web console in the Zoom On-Premise Meeting Connector before version 4.6.239.20200613, Zoom On-Premise Meeting Connector MMR before version 4.6.239.20200613, Zoom On-Premise Recording Connector before version 3.8.42.20200905, Zoom On-Premise Virtual Room Connector before version 4.4.6344.20200612, and Zoom On-Premise Virtual Room Connector Load Balancer before version 2.5.5492.20200616 fails to validate that a NULL byte was sent while authenticating. This could lead to a crash of the login service.

In PHP versions 7.3.x below 7.3.27, 7.4.x below 7.4.15 and 8.0.x below 8.0.2, when using SOAP extension to connect to a SOAP server, a malicious SOAP server could return malformed XML data as a response that would cause PHP to access a null pointer and thus cause a crash.

There is a NULL pointer dereference vulnerability in some Huawei products. An attacker may send specially crafted POST messages to the affected products. Due to insufficient validation of some parameter in the message, successful exploit may cause some process abnormal. (Vulnerability ID: HWPSIRT-2017-10105) This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2020-9085.

Unchecked Return Value to NULL Pointer Dereference vulnerability in Open Networking Foundation (ONF) libfluid (libfluid_msg module). This vulnerability is associated with program routine fluid_msg::QueuePropertyList::unpack10. This issue affects libfluid: 0.1.0.

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix NULL pointer dereference in sk_psock_verdict_data_ready() syzbot reported the following NULL pointer dereference issue [1]: BUG: kernel NULL pointer dereference, address: 0000000000000000 [...] RIP: 0010:0x0 [...] Call Trace: <TASK> sk_psock_verdict_data_ready+0x232/0x340 net/core/skmsg.c:1230 unix_stream_sendmsg+0x9b4/0x1230 net/unix/af_unix.c:2293 sock_sendmsg_nosec net/socket.c:730 [inline] __sock_sendmsg+0x221/0x270 net/socket.c:745 ____sys_sendmsg+0x525/0x7d0 net/socket.c:2584 ___sys_sendmsg net/socket.c:2638 [inline] __sys_sendmsg+0x2b0/0x3a0 net/socket.c:2667 do_syscall_64+0xf9/0x240 entry_SYSCALL_64_after_hwframe+0x6f/0x77 If sk_psock_verdict_data_ready() and sk_psock_stop_verdict() are called concurrently, psock->saved_data_ready can be NULL, causing the above issue. This patch fixes this issue by calling the appropriate data ready function using the sk_psock_data_ready() helper and protecting it from concurrency with sk->sk_callback_lock.

A null pointer dereference issue was discovered in 'FFmpeg' in decode_main_header() function of libavformat/nutdec.c file. The flaw occurs because the function lacks check of the return value of avformat_new_stream() and triggers the null pointer dereference error, causing an application to crash.
