dma-buf: insert memory barrier before updating num_fences
smp_store_mb() inserts memory barrier after storing operation. It is different with what the comment is originally aiming so Null pointer dereference can be happened if memory update is reordered.

GHSA-Q5G9-GXXP-QXH7
Vulnerability from github – Published: 2024-03-25 12:30 – Updated: 2025-03-03 18:31In the Linux kernel, the following vulnerability has been resolved:
serial: rp2: use 'request_firmware' instead of 'request_firmware_nowait'
In 'rp2_probe', the driver registers 'rp2_uart_interrupt' then calls 'rp2_fw_cb' through 'request_firmware_nowait'. In 'rp2_fw_cb', if the firmware don't exists, function just return without initializing ports of 'rp2_card'. But now the interrupt handler function has been registered, and when an interrupt comes, 'rp2_uart_interrupt' may access those ports then causing NULL pointer dereference or other bugs.
Because the driver does some initialization work in 'rp2_fw_cb', in order to make the driver ready to handle interrupts, 'request_firmware' should be used instead of asynchronous 'request_firmware_nowait'.
This report reveals it:

Vulnerability from github – Published: 2022-05-13 01:01 – Updated: 2025-04-20 03:33An exploitable denial-of-service vulnerability exists in the fabric-worker component of Aerospike Database Server 3.10.0.3. A specially crafted packet can cause the server process to dereference a null pointer. An attacker can simply connect to a TCP port in order to trigger this vulnerability.

Vulnerability from github – Published: 2025-09-16 18:31 – Updated: 2025-12-10 21:31In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Enhance sanity check while generating attr_list
ni_create_attr_list uses WARN_ON to catch error cases while generating attribute list, which only prints out stack trace and may not be enough. This repalces them with more proper error handling flow.

Mitigation MIT-56
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Select a programming language that is not susceptible to these issues.
Mitigation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
