The openSUSE Leap 15.0 was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2019-2024: A use-after-free when disconnecting a source was fixed which could lead to crashes. bnc#1129179).
• CVE-2019-3819: A flaw was found in the Linux kernel in the function hid_debug_events_read() in drivers/hid/hid-debug.c file which may enter an infinite loop with certain parameters passed from a userspace. A local privileged user ('root') can cause a system lock up and a denial of service. Versions from v4.18 and newer are vulnerable (bnc#1123161).
• CVE-2019-7308: kernel/bpf/verifier.c performed undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks (bnc#1124055).
• CVE-2019-8912: af_alg_release() in crypto/af_alg.c neglected to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr (bnc#1125907).
• CVE-2019-8980: A memory leak in the kernel_read_file function in fs/exec.c allowed attackers to cause a denial of service (memory consumption) by triggering vfs_read failures (bnc#1126209).
• CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166).
