CVE-2024-40948: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: mm/pagetablecheck: fix crash on ZONEDEVICE Not all pages may apply to pgtable check. One example is ZONEDEVICE pages: they map PFNs directly, and they don't allocate pageext at all even if there's struct page around. One may...

CVE-2022-48731 mm/kmemleak: avoid scanning potential huge holes

CVE-2022-48731

The Linux kernel contains a vulnerability in the mm/kmemleak component where scanning potential huge holes can cause a soft lockup . When using devm_request_free_mem_region() and devm_memremap_pages() to add ZONE_DEVICE memory, a huge end PFN (e.g., 0x400000000) creates a massive gap between node...

CVE-2023-52489

In the Linux kernel, the following vulnerability has been resolved: mm/sparsemem: fix race in accessing memorysection-usage The below race is observed on a PFN which falls into the device memory region with the system memory configuration where PFN's are such that ZONENORMAL ZONEDEVICE ZONENORMAL...

CVE-2023-52489

CVE-2023-52489 is tied to a Linux kernel race in mm/sparsemem memory sections (memory_section->usage) when PFNs span ZONE_NORMAL, ZONE_DEVICE, ZONE_NORMAL and memory compaction runs. The race occurs between pfn_valid()/pfn_section_valid() and section_deactivate, where ms->usage can be NULL ...
