Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mm/damon/core: initialize damo_filter-&gt;list from damos_new_filter()<br /> <br /> damos_new_filter() is not initializing the list field of newly allocated<br /> filter object. However, DAMON sysfs interface and DAMON_RECLAIM are not<br /> initializing it after calling damos_new_filter(). As a result, accessing<br /> uninitialized memory is possible. Actually, adding multiple DAMOS filters<br /> via DAMON sysfs interface caused NULL pointer dereferencing. Initialize<br /> the field just after the allocation from damos_new_filter().
