Summary
CVE-2024-56673: A vulnerability in the Linux kernel's RISC-V architecture affects the vmemmap page tables. These tables use an unconventional method for allocation, which leads to the pmd destructor being unintentionally called during teardown, resulting in a crash. This issue was discovered during HMM selftests and can cause a kernel panic. To mitigate this issue, a check should be added to avoid calling the pmd destructor when the context is vmemmap_free().
