August 28, 2018
An update that solves four vulnerabilities and has 52 fixes is now available
Summary
The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2018-15572: The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517 bnc#1105296). - CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation (bnc#1105322).
