Description Robert Frohl 2019-11-20 13:44:13 UTC 
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.

Comment 1 Robert Frohl 2019-11-20 13:45:32 UTC 
pretty similar to bsc#1157333

only seems relevant for SLE15-SP2
Comment 2 Takashi Iwai 2019-11-20 14:01:27 UTC 
Will backport once when the fix gets merged to Linus tree.

This one is indeed only in SLE15-SP2 and later.
Comment 3 Takashi Iwai 2019-11-26 10:07:13 UTC 
Backported to SLE15-SP2 branch.

Reassigned back to security team.
