A memory leak in the crypto_report() function in crypto/crypto_user_base.c
in the Linux kernel through 5.3.11 allows attackers to cause a denial of
service (memory consumption) by triggering crypto_report_alg() failures,
aka CID-ffdde5932042.

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).
