"According to the version of the kernel packages installed, the
EulerOS Virtualization installation on the remote host is affected by
the following vulnerability :
- A flaw was found in the Linux Kernel in the
ucma_leave_multicast() function in
drivers/infiniband/core/ucma.c which allows access to a
certain data structure after freeing it in
ucma_process_join(). This allows an attacker to cause a
use-after-free bug and to induce kernel memory
corruption, leading to a system crash or other
unspecified impact. Due to the nature of the flaw,
privilege escalation cannot be fully ruled out,
although we believe it is unlikely.(CVE-2018-14734)
