CVE-2026-98092 Linux CVE debrief

Who should care

Linux kernel developers and maintainers, as well as users of Linux-based systems that utilize the ASoC component, should be aware of this vulnerability and take necessary precautions. This vulnerability may affect operators who manage Linux-based systems, platform administrators who maintain kernel components, and security teams who monitor system stability and memory usage.

Why it matters

A memory leak vulnerability in the Linux kernel's ASoC component requires attention from Linux kernel developers and users of Linux-based systems.

• Memory leak can lead to increased memory usage and potential system instability.
• Local attackers may be able to exploit this vulnerability to cause a denial of service.

Technical summary

The `acp6x_pdm_dma_close()` function in the Linux kernel's ASoC component does not free the `runtime->private_data` buffer allocated in `acp6x_pdm_dma_open()`, leading to a memory leak. A patch has been applied to fix this issue. The vulnerability is specific to a particular kernel component and requires local access to exploit. Linux kernel developers and maintainers should review the patch and apply it to affected systems. Users of Linux-based systems that utilize the ASoC component should also be aware of this vulnerability and take necessary precautions.

Defensive priority

Low priority, as the vulnerability is specific to a particular kernel component and requires local access to exploit.

Recommended defensive actions

• Review the Linux kernel patch repository for the fix and apply it to affected systems.
• Monitor system memory usage for potential issues related to the memory leak.
• Consider implementing additional memory monitoring and leak detection tools.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.

Evidence notes

The CVE record and NVD entry provide limited information about the vulnerability. The Linux kernel patch repository provides additional details about the fix. A memory leak vulnerability was found in the Linux kernel's ASoC component, specifically in the amd yc driver. The `acp6x_pdm_dma_close()` function does not free the `runtime->private_data` buffer allocated in `acp6x_pdm_dma_open()`, leading to a memory leak. This issue has been resolved with a patch that adds the missing `kfree()` call. Evidence limits suggest that affected and
