Advisory Release Date: 2020-03-02 23:44 Pacific
Advisory Updated Date: 2020-03-06 22:38 Pacific
Severity: Important

Issue Overview:

In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b. (CVE-2019-20096)

An issue was discovered in the Linux kernel before 5.0.10. SMB2_negotiate in fs/cifs/smb2pdu.c has an out-of-bounds read because data structures are incompletely updated after a change from smb30 to smb21. (CVE-2019-15918)
