Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak occurs in the DAMON sysfs component. The damon call() function for repeat call control of DAMON SYSFS may fail if the kdamond is stopped before the function is invoked. This scenario can happen when a damon context is created to monitor virtual address processes and the process terminates immediately. In such cases, the dynamically allocated repeat call control is not deallocated.
