According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.(CVE-2020-16166)
The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.(CVE-2020-12888)
In the Linux kernel through 5.7.6, usbtest_disconnect in drivers/usb/misc/usbtest.c has a memory leak, aka CID-28ebeb8db770.(CVE-2020-15393)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
