CVE-2019-19045: A memory leak in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c allowed attackers to cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures (bnc#1161522).

CVE-2019-16994: A memory leak existed in sit_init_net() in net/ipv6/sit.c which might have caused denial of service (bnc#1161523).

CVE-2019-19054: A memory leak in the cx23888_ir_probe() function in drivers/media/pci/cx23885/cx23888-ir.c allowed attackers to cause a denial of service (memory consumption) by triggering kfifo_alloc() failures (bnc#1161518).

CVE-2019-14896: A heap overflow was found in the add_ie_rates() function of the Marvell Wifi Driver (bsc#1157157).

CVE-2019-20095: Fixed a memory leak and denial of service in mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c, where some error-handling cases did not free allocated hostcmd memory (bnc#1159909).

CVE-2019-20054: Fixed a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c related to put_links (bnc#1159910).

CVE-2019-19966: Fixed a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service (bnc#1159841).

CVE-2019-19447: Mounting a crafted ext4 filesystem image, performing some operations, and unmounting could have led to a use-after-free in fs/ext4/super.c (bnc#1158819).

CVE-2019-19319: A setxattr operation, after a mount of a crafted ext4 image, could cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call (bnc#1158021).

CVE-2019-19767: The Linux kernel mishandled ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c (bnc#1159297).

CVE-2019-18808: A memory leak in the ccp_run_sha_cmd() in drivers/crypto/ccp/ccp-ops.c allowed attackers to cause a denial of service (memory consumption) (bnc#1156259).

CVE-2019-19066: A memory leak in the bfad_im_get_stats() in drivers/scsi/bfa/bfad_attr.c allowed attackers to cause a denial of service (memory consumption) by triggering bfa_port_get_stats() failures (bnc#1157303).
