   An update that fixes one vulnerability is now available.


   This update for the Linux Kernel 4.12.14-25_3 fixes one issue.

   The following security issue was 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).
