  "description": "In the Linux kernel, the following vulnerability has been resolved:  mm/damon/sysfs: fix wrong empty schemes assumption under online tuning in damon_sysfs_set_schemes()  Commit da87878010e5 (\u0022mm/damon/sysfs: support online inputs update\u0022) made \u0027damon_sysfs_set_schemes()\u0027 to be called for running DAMON context, which could have schemes.  In the case, DAMON sysfs interface is supposed to update, remove, or add schemes to reflect the sysfs files.  However, the code is assuming the DAMON context wouldn\u0027t have schemes at all, and therefore creates and adds new schemes.  As a result, the code doesn\u0027t work as intended for online schemes tuning and could have more than expected memory footprint.  The schemes are all in the DAMON context, so it doesn\u0027t leak the memory, though.  Remove the wrong asssumption (the DAMON context wouldn\u0027t have schemes) in \u0027damon_sysfs_set_schemes()\u0027 to fix the bug.",
