CVE-2026-97910 Linux CVE debrief

Who should care

Linux kernel developers and administrators who use the ASoC sprd component should review and apply the provided patches to prevent potential buffer overflows. Additionally, security teams and vulnerability management teams should be aware of this vulnerability and take steps to mitigate the risk of exploitation. Operators of systems that use the ASoC sprd component should also be aware of this vulnerability and take steps to ensure that their systems are

Why it matters

A local user can trigger a buffer overflow in the Linux kernel's ASoC sprd component by providing a large compress buffer size, allowing for potential code execution or data corruption. Linux kernel developers and administrators who use the ASoC sprd component should review and apply the provided patches to prevent potential buffer overflows.

• Potential code execution or data corruption due to buffer overflow
• Increased risk of system compromise or data loss
• Need for patching and remediation efforts

Technical summary

The Linux kernel's ASoC sprd component does not validate compress buffer sizes against fixed allocations, allowing a local user to overflow the buffer. A fix has been applied to reject parameters that do not fit into the fixed buffers. The vulnerability is caused by the component's failure to validate compress buffer sizes, which can lead to a buffer overflow and potentially allow for code execution or data corruption. The fix involves rejecting parameters that do not fit into the fixed buffers, which can prevent the buffer overflow and mitigate the risk of exploitation.

Defensive priority

High

Recommended defensive actions

• Review and apply the provided kernel patches to fix the buffer overflow vulnerability
• Restrict access to the affected component to only trusted users
• Monitor system logs for potential exploitation attempts
• Perform regular vulnerability assessments to identify potential vulnerabilities
• Implement compensating controls to mitigate the risk of exploitation
• Track exceptions and retest remediated assets to ensure the vulnerability is fully resolved
