CVE-2025-38676 Details
Description
In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Avoid stack buffer overflow from kernel cmdline While the kernel command line is considered trusted in most environments, avoid writing 1 byte past the end of "acpiid" if the "str" argument is maximum length.
A stack buffer overflow vulnerability has been addressed in the Linux kernel's IOMMU/AMD component. This issue arose from the kernel command line processing, where it inadvertently wrote beyond the allocated buffer for the 'acpiid' parameter. Although the kernel command line is generally trusted, this vulnerability could lead to a buffer overflow by allowing a maximum-length 'str' argument to overwrite memory.
