Description

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Add a length limitation for the ivrs_acpihid command-line parameter The 'acpiid' buffer in the parse_ivrs_acpihid function may overflow, because the string specifier in the format string sscanf() has no width limitation. Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with SVACE.
