CVE-2024-41055 is a Linux kernel memory-management flaw in pfn_section_valid(). A prior race fix added an atomic read of memory_section usage data to address concurrent section deactivation, but the retrieved pointer could still be cleared before it was dereferenced. Consequently, pfn_section_valid() could dereference a NULL usage pointer. The upstream correction validates the usage pointer before dereferencing it.
