PT-2025-3662 · Linux · Linux Kernel

The vulnerable software is the Linux kernel. The issue arose from a regression in the kernel's memory management subsystem, specifically in the handling of write-sealed memfd mappings. The problem was introduced by a commit that moved a check for mapping writability before the shmem mmap hook was...

mm: avoid leaving partial pfn mappings around in error case

...

kernel: ACPICA: Revert "ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine."

A vulnerability was found in the Linux kernel's ACPICA component, where improper handling of memory mappings can lead to a NULL pointer dereference. This issue arises when mapping requests exceed page boundaries, resulting in attempts to access unmapped memory...

kernel: drm/i915/dpt: Make DPT object unshrinkable

In the Linux kernel, the following vulnerability has been resolved: drm/i915/dpt: Make DPT object unshrinkable In some scenarios, the DPT object gets shrunk but the actual framebuffer did not and thus its still there on the DPT's vm-boundlist. Then it tries to rewrite the PTEs via a stale CPU...

CVE-2024-50066

In the Linux kernel, the following vulnerability has been resolved: mm/mremap: fix movenormalpmd/retractpagetables race In mremap, movepagetables looks at the type of the PMD entry and the specified address range to figure out by which method the next chunk of page table entries should be moved. ...

CVE-2024-50066 mm/mremap: fix move_normal_pmd/retract_page_tables race

In the Linux kernel, the following vulnerability has been resolved: mm/mremap: fix movenormalpmd/retractpagetables race In mremap, movepagetables looks at the type of the PMD entry and the specified address range to figure out by which method the next chunk of page table entries should be moved. ...

CVE-2024-50066

CVE-2024-50066 is a Linux kernel race in mm/mremap where move_page_tables can race with retract_page_tables under THP/rmap locking. The flaw stems from reading the PMD type before acquiring rmap locks, potentially creating bogus PMD entries (e.g., mapping page 0 as a page table on x86) and enabli...
