"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/damon/core: disallow non-power of two min_region_sz on damon_start()\n\nCommit d8f867fa0825 (\"mm/damon: add damon_ctx->min_sz_region\") introduced\na bug that allows unaligned DAMON region address ranges. Commit\nc80f46ac228b (\"mm/damon/core: disallow non-power of two min_region_sz\")\nfixed it, but only for damon_commit_ctx() use case. Still, DAMON sysfs\ninterface can emit non-power of two min_region_sz via damon_start(). Fix\nthe path by adding the is_power_of_2() check on damon_start().\n\nThe issue was discovered by sashiko [1]."
