A memory leak in the crypto_reportstat() function in crypto/crypto_user_stat.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_reportstat_alg() failures, aka CID-c03b04dcdba1.
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
