CVE-2022-50320 ACPI: tables: FPDT: Don't call acpi_os_map_memory() on invalid phys address

In the Linux kernel, the following vulnerability has been resolved: ACPI: tables: FPDT: Don't call acpiosmapmemory on invalid phys address On a Packard Bell Dot SC Intel Atom N2600 model there is a FPDT table which contains invalid physical addresses, with high bits set which fall outside the ran...

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-2023-53248

CVE-2023-53248 affects the Linux kernel DRM/AMDGPU subsystem. The fix installs a stub fence into potentially unused page-table update fences instead of NULL to avoid NULL dereferences when dma_fence_wait() is called on those pointers during CPU-based page-table updates. This targets the scenario ...
