CVE-2026-98053

/// Technical description

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

ASoC: Intel: avs: Refactor and fix init_config access

Existing code accesses enties found in ->init_configs array through

indexes that are part of ->config_ids array. Those two are limited by:

->num_init_configs and ->num_config_ids respectively. Using ID larger

or equal to ->num_init_configs leads to out-of-bounds access:

avs_path_module_send_init_configs()

loop:

(...) &acomp->tplg->init_configs[ids[i]]

^ out-of-bounds candidate

Rather than adding another if-statement, refactor the code. There is no

need to store the IDs, have a list of pointers to actual config-entries

instead. As the verification of ->init_config entries does not differ from

verification of other types that are part of the topology.c file, simply

reuse the code.

/// Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
