Description

Security update for the Linux Kernel (Live Patch 2 for SLE 15) This update for the Linux Kernel 4.12.14-25_6 fixes several issues. The following security issues were fixed: - CVE-2018-15471: An issue was discovered in xenvif_set_hash_mapping in drivers/net/xen-netback/hash.c. The Linux netback driver allowed frontends to control mapping of requests to request queues. When processing a request to set or change this mapping, some input validation (e.g., for an integer overflow) was missing or flawed, leading to OOB access in hash handling. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in one or more of privilege escalation, Denial of Service (DoS), or information leaks (bsc#1105026). - CVE-2018-10853: A KVM guest userspace to guest kernel write was fixed, which could be used by guest users to crash the guest kernel (bsc#1097108).
