The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2020-8992: An issue was discovered in ext4_protect_reserved_inode in fs/ext4/block_validity.c that allowed attackers to cause a soft lockup via a crafted journal size (bnc#1164069). - CVE-2020-8648: There was a use-after-free vulnerability in the n_tty_receive_buf_common function in drivers/tty/n_tty.c (bnc#1162928). - CVE-2019-16746: An issue was discovered in net/wireless/nl80211.c. It did not check the length of variable elements in a beacon head, leading to a buffer overflow (bnc#1152107). - CVE-2020-8428: There was a use-after-free bug in fs/namei.c, which allowed local users to cause a denial of service (OOPS) or possibly obtain sensitive information from kernel memory, aka CID-d0cb50185ae9 (bnc#1162109). - 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, aka CID-c8c2a057fdc7 (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, aka CID-07f12b26e21a (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, aka CID-a7b2df76b42b (bnc#1161518). - CVE-2019-14896: A heap-based buffer overflow vulnerability was found in the Marvell WiFi driver.
