UBUNTU-CVE-2023-54057

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Add a length limitation for the ivrsacpihid command-line parameter The 'acpiid' buffer in the parseivrsacpihid function may overflow, because the string specifier in the format string sscanf has no width limitation...

CVE-2025-38676

CVE-2025-38676 affects the Linux kernel (iommu/amd) and fixes a stack buffer overflow when processing kernel cmdline acpiid length. The issue is local and can be triggered by crafted kernel command-line input; base score 7.8 (HIGH) with LOCAL/LOW complexity, no user interaction. The CVE is addres...

kernel: iommu/amd: Add a length limitation for the ivrs_acpihid command-line parameter

A stack buffer overflow vulnerability was found in the Linux kernel's AMD IOMMU driver. The parseivrsacpihid function uses sscanf to parse the ivrsacpihid kernel command-line parameter without specifying a field width limit. An overly long ACPI HID string can overflow the fixed-size acpiid buffer...
