CVE-2026-98053: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 6.9, before 6.18.53 (fixed in 6.18.53); from 6.19, before 7.2.7 (fixed in 7.2.7); version 7.3 only
