- Summary
- mm/mincore: handle non-swap entries before !CONFIG_SWAP guard
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mm/mincore: handle non-swap entries before !CONFIG_SWAP guard
mincoreswap() also fields migration/hwpoison entries (and shmem swapin-error entries), which can exist on !CONFIGSWAP builds when CONFIGMIGRATION or CONFIGMEMORYFAILURE is enabled. The !ISENABLED(CONFIGSWAP) guard ran before the non-swap-entry early return, so mincorepterange() can spuriously WARN and report these pages nonresident on !CONFIGSWAP 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.
