CVE-2026-68475 Linux CVE debrief

A memory region leak vulnerability has been identified in the Linux kernel's sunxi reset driver. The issue arises when the ioremap() function fails in the sunxi_reset_init() function, resulting in a resource leak due to the failure to release the memory region obtained via request_mem_region(). This vulnerability can cause memory leaks and potentially lead to denial-of-service (DoS) attacks or other security issues if exploited. Linux kernel developers and maintainers should review the Linux kernel configurations and versions for potential exposure and apply patches to fix the memory region leak. The affected scope and potential impact on Linux-based systems should be verified, and relevant monitoring, detection, and logs for exposed assets should be checked. Evidence of the vulnerability's impact and the effectiveness of the patches should be documented.

Who should care

Linux kernel developers and maintainers, Linux distribution vendors, users of Linux-based systems, security teams responsible for vulnerability management and patching, and operators of Linux-based infrastructure. These parties should review the Linux kernel configurations and versions for potential exposure, apply patches to fix the memory region leak, monitor Linux kernel updates for future security patches, and verify the affected scope and potential impact on their systems.

Technical summary

The Linux kernel's sunxi reset driver has a memory region leak vulnerability. When ioremap() fails in sunxi_reset_init(), the memory region obtained via request_mem_region() is not released, leading to a resource leak. This vulnerability can be mitigated by applying patches to fix the memory region leak. Linux kernel developers and maintainers should review the Linux kernel configurations and versions for potential exposure and monitor Linux kernel updates for future security patches.

Defensive priority

Apply patches to fix memory region leak in sunxi reset driver

Recommended defensive actions

  • Apply patches to fix memory region leak in sunxi reset driver
  • Review Linux kernel configurations and versions for potential exposure
  • Monitor Linux kernel updates for future security patches
  • Perform a thorough review of the Linux kernel source code to identify potential similar vulnerabilities
  • Verify the affected scope and potential impact on Linux-based systems
  • 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 detail provide information on the vulnerability. However, the source detail is thin, and further verification is required to confirm the affected scope and potential impact. Linux kernel developers should verify the affected versions and configurations, review the Linux kernel source code, and assess the vulnerability's impact on their systems. The memory region leak vulnerability in the sunxi reset driver is caused by the failure to release the memory region obtained via request_mem_region() when ioremap() fails in sunxi_reset_init().
