8.8 · HIGHOverview
CVE-2024-57999 is a high-severity vulnerability affecting linux linux_kernel. It was published on February 27, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pseries/iommu: IOMMU incorrectly marks MMIO range in DDW
Power Hypervisor can possibily allocate MMIO window intersecting with
Dynamic DMA Window (DDW) range, which is over 32-bit addressing.
These MMIO pages needs to be marked as reserved so that IOMMU doesn't map
DMA buffers in this range.
The current code is not marking these pages correctly which is resulting
in LPAR to OOPS while booting. The stack is at below
