Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.3.11

Description The issue is related to a memory leak in the crypto reportstat() function, which can be triggered by causing crypto reportstat alg() failures. This can lead to a denial of service due to memory consumption. The problem is associated with uncontrolled resource expenditure.
