CVE-2019-19050
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.08%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
