CVE-2016-9604 (GCVE-0-2016-9604)
Vulnerability from cvelistv5 – Published: 2018-07-11 13:00 – Updated: 2024-08-06 02:59
VLAI?
Summary
It was discovered in the Linux kernel before 4.11-rc8 that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring. This allows root to bypass module signature verification by adding a new public key of its own devising to the keyring.

CVE-2018-1087 (GCVE-0-2018-1087)
Vulnerability from cvelistv5 – Published: 2018-05-15 16:00 – Updated: 2024-08-05 03:51
VLAI?
Summary
kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest.

CVE-2018-1118 (GCVE-0-2018-1118)
Vulnerability from cvelistv5 – Published: 2018-05-10 22:00 – Updated: 2024-08-05 03:51
VLAI?
Summary
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
