CVE-2026-53333 Detail

Description

In the Linux kernel, the following vulnerability has been resolved: mm/mincore: handle non-swap entries before !CONFIG_SWAP guard mincore_swap() also fields migration/hwpoison entries (and shmem swapin-error entries), which can exist on !CONFIG_SWAP builds when CONFIG_MIGRATION or CONFIG_MEMORY_FAILURE is enabled. The !IS_ENABLED(CONFIG_SWAP) guard ran before the non-swap-entry early return, so mincore_pte_range() can spuriously WARN and report these pages nonresident on !CONFIG_SWAP kernels. Move the guard below the non-swap-entry check so only true swap entries trip the WARN, and migration/hwpoison entries take the existing "uptodate / non-shmem" path.
