CVE-2022-50320

The CVE-2022-50320 issue is a Linux kernel ACPI FPDT FPDT table bug where invalid physical addresses trigger ioremap warnings and an oops. The root cause is calling acpi_os_map_memory() on an invalid phys address; a fix adds a validation step to prevent mapping invalid addresses. The description ...

CVE-2023-53247

CVE-2023-53247 involves the Linux kernel Btrfs code (btrfs_cont_expand path). The issue arises when a page is retrieved during btrfs_cont_expand, then marked as mapped and read; if release_folio() is called before reacquiring the page lock, release_folio() may clear the page private flag but leav...

CVE-2023-53171

CVE-2023-53171 affects the Linux kernel’s vfio/type1 path. The issue occurs when a vfio container is preserved across execs: the task’s mm can change to a new mm with locked_vm=0, causing undercounted DMA mappings and a later unmap to underflow locked_vm, leading to ENOMEM on a subsequent dma map...

CVE-2022-50257

The CVE-2022-50257 issue is in the Linux kernel Xen grant handling (xen/gntdev) where partial grant mapping failures could leak grants. In paravirtualized domains (use_ptemod = true), alloced was not updated for all successful map_ops or kmap_ops, risking incorrect live_grants and leaks. The fix ...
