The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bnc#1108399). - CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable (bnc#1107829). The following non-security bugs were fixed: - alsa: bebob: fix memory leak for M-Audio FW1814 and ProjectMix I/O at error path (bsc#1051510). - alsa: bebob: use address returned by kmalloc() instead of kernel stack for streaming DMA mapping (bsc#1051510). -
