AI Translation Available
In the Linux kernel, the following vulnerability has been resolved:
mm/damon/core: disallow non-power of two min_region_sz on damon_start()
Commit d8f867fa0825 ('mm/damon: add damon_ctx->min_sz_region') introduced
a bug that allows unaligned DAMON region address ranges. Commit
c80f46ac228b ('mm/damon/core: disallow non-power of two min_region_sz')
fixed it, but only for damon_commit_ctx() use case. Still, DAMON sysfs
interface can emit non-power of two min_region_sz via damon_start(). Fix
the path by adding the is_power_of_2() check on damon_start().
The issue was discovered by sashiko [1].
