Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
mm/damon/core: initialize damo_filter->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().
