The vulnerability of the functions damon_call() and kdamond_fn() in the mm/damon/core.c module of the Linux operating system’s memory management subsystem allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the damoncall and kdamondfn functions in the mm/damon/core.c module of the Linux kernel’s memory management subsystem is related to the repeated use of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity,...
