Vulnerability from github – Published: 2026-04-24 15:32 – Updated: 2026-04-28 15:30

Details

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

ALSA: usx2y: us144mkii: fix NULL deref on missing interface 0

A malicious USB device with the TASCAM US-144MKII device id can have a configuration containing bInterfaceNumber=1 but no interface 0. USB configuration descriptors are not required to assign interface numbers sequentially, so usb_ifnum_to_if(dev, 0) returns will NULL, which will then be dereferenced directly.

Fix this up by checking the return value properly.

Severity

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

tipc: Check the bearer type before calling tipc_udp_nl_bearer_add()

syzbot reported the following general protection fault [1]:

general protection fault, probably for non-canonical address 0xdffffc0000000010: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000080-0x0000000000000087] ...

The cause of this issue is that when tipc_nl_bearer_add() is called with the TIPC_NLA_BEARER_UDP_OPTS attribute, tipc_udp_nl_bearer_add() is called even if the bearer is not UDP.

tipc_udp_is_known_peer() called by tipc_udp_nl_bearer_add() assumes that the media_ptr field of the tipc_bearer has an udp_bearer type object, so the function goes crazy for non-UDP bearers.

This patch fixes the issue by checking the bearer type before calling tipc_udp_nl_bearer_add() in tipc_nl_bearer_add().

A vulnerability has been identified in SIMATIC S7-PLCSIM V5.4 (All versions). An attacker with local access to the system could cause a Denial-of-Service condition in the application when it is used to open a specially crafted file. As a consequence, a NULL pointer deference condition could cause the application to terminate unexpectedly and must be restarted to restore the service.

GHSA-JGC9-FR2G-9R52

Vulnerability from github – Published: 2026-05-01 15:30 – Updated: 2026-05-07 21:30
VLAI
Details

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

comedi: ni_atmio16d: Fix invalid clean-up after failed attach

If the driver's COMEDI "attach" handler function (atmio16d_attach()) returns an error, the COMEDI core will call the driver's "detach" handler function (atmio16d_detach()) to clean up. This calls reset_atmio16d() unconditionally, but depending on where the error occurred in the attach handler, the device may not have been sufficiently initialized to call reset_atmio16d(). It uses dev->iobase as the I/O port base address and dev->private as the pointer to the COMEDI device's private data structure. dev->iobase may still be set to its initial value of 0, which would result in undesired writes to low I/O port addresses. dev->private may still be NULL, which would result in null pointer dereferences.

Fix atmio16d_detach() by checking that dev->private is valid (non-null) before calling reset_atmio16d(). This implies that dev->iobase was set correctly since that is set up before dev->private.

Severity
5.5 (Medium)

Mitigation MIT-56
Implementation

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
Requirements

Select a programming language that is not susceptible to these issues.

Mitigation
Implementation

Check the results of all functions that return a value and verify that the value is non-null before acting upon it.

Mitigation
Architecture and Design

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
Implementation

Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.

No CAPEC attack patterns related to this CWE.
