CVE-2024-53111

CVE-2024-53111 affects the Linux kernel on 32-bit platforms, in the mremap path (mm/mremap: fix address wraparound in move_page_tables). The bug could misdetect success when copying PTEs due to a wraparound in len + old_addr

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

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...
