Vulnerability Details CVE-2023-53555
In the Linux kernel, the following vulnerability has been resolved:
mm/damon/core: initialize damo_filter->list from damos_new_filter()
damos_new_filter() is not initializing the list field of newly allocated
filter object. However, DAMON sysfs interface and DAMON_RECLAIM are not
initializing it after calling damos_new_filter(). As a result, accessing
uninitialized memory is possible. Actually, adding multiple DAMOS filters
via DAMON sysfs interface caused NULL pointer dereferencing. Initialize
the field just after the allocation from damos_new_filter().
