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

eth: mlx4: Fix IS_ERR() vs NULL check bug in mlx4_en_create_rx_ring

Replace NULL check with IS_ERR() check after calling page_pool_create() since this function returns error pointers (ERR_PTR). Using NULL check could lead to invalid pointer dereference.

GHSA-X738-FP96-2H57

Vulnerability from github – Published: 2025-07-04 15:31 – Updated: 2025-11-18 18:32
VLAI
Details

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

configfs-tsm-report: Fix NULL dereference of tsm_ops

Unlike sysfs, the lifetime of configfs objects is controlled by userspace. There is no mechanism for the kernel to find and delete all created config-items. Instead, the configfs-tsm-report mechanism has an expectation that tsm_unregister() can happen at any time and cause established config-item access to start failing.

That expectation is not fully satisfied. While tsm_report_read(), tsm_report_{is,is_bin}_visible(), and tsm_report_make_item() safely fail if tsm_ops have been unregistered, tsm_report_privlevel_store() tsm_report_provider_show() fail to check for ops registration. Add the missing checks for tsm_ops having been removed.

Now, in supporting the ability for tsm_unregister() to always succeed, it leaves the problem of what to do with lingering config-items. The expectation is that the admin that arranges for the ->remove() (unbind) of the ${tsm_arch}-guest driver is also responsible for deletion of all open config-items. Until that deletion happens, ->probe() (reload / bind) of the ${tsm_arch}-guest driver fails.

This allows for emergency shutdown / revocation of attestation interfaces, and requires coordinated restart.

GHSA-X78H-GF69-P5J6

Vulnerability from github – Published: 2026-05-27 12:31 – Updated: 2026-06-26 21:32
VLAI
Details

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

bpf: fix end-of-list detection in cgroup_storage_get_next_key()

list_next_entry() never returns NULL -- when the current element is the last entry it wraps to the list head via container_of(). The subsequent NULL check is therefore dead code and get_next_key() never returns -ENOENT for the last element, instead reading storage->key from a bogus pointer that aliases internal map fields and copying the result to userspace.

Replace it with list_entry_is_head() so the function correctly returns -ENOENT when there are no more entries.

Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-11-03 21:31

Details

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

media: imx-jpeg: Ensure power suppliers be suspended before detach them

The power suppliers are always requested to suspend asynchronously, dev_pm_domain_detach() requires the caller to ensure proper synchronization of this function with power management callbacks. otherwise the detach may led to kernel panic, like below:

Details

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

ASoC: imx-audmix: Add NULL check in imx_audmix_probe

devm_kasprintf() can return a NULL pointer on failure,but this returned value in imx_audmix_probe() is not checked. Add NULL check in imx_audmix_probe(), to handle kernel NULL pointer dereference error.

Details

A NULL pointer dereference flaw was found in the megasas-gen2 SCSI host bus adapter emulation of QEMU in versions before and including 6.0. This issue occurs in the megasas_command_cancelled() callback function while dropping a SCSI request. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

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.
