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.

It was discovered that the crypto subsystem in the Linux kernel did not
properly deallocate memory in certain error conditions. A local attacker
could use this to cause a denial of service (kernel memory exhaustion).
