GHSA-P285-VXM3-73M7
Vulnerability from github – Published: 2025-05-08 09:30 – Updated: 2025-11-13 00:30In the Linux kernel, the following vulnerability has been resolved:
cpufreq: apple-soc: Fix null-ptr-deref in apple_soc_cpufreq_get_rate()
cpufreq_cpu_get_raw() can return NULL when the target CPU is not present in the policy->cpus mask. apple_soc_cpufreq_get_rate() does not check for this case, which results in a NULL pointer dereference.

GHSA-P2VV-2726-R3PR
Vulnerability from github – Published: 2025-10-04 09:30 – Updated: 2026-01-23 21:30In the Linux kernel, the following vulnerability has been resolved:

Preparing the DAI for sink graph continues though and next call to q6apm_lpass_dai_prepare() receives dai_data->graph[dai->id]=NULL leading to NULL pointer exception:

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.
