CVE-2018-16884 (GCVE-0-2018-16884)
Vulnerability from cvelistv5 – Published: 2018-12-18 22:00 – Updated: 2024-08-05 10:32
VLAI?
Summary
A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.

CVE-2018-14646 (GCVE-0-2018-14646)
Vulnerability from cvelistv5 – Published: 2018-11-26 19:00 – Updated: 2024-08-05 09:38
VLAI?
Summary
The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service.

CVE-2017-7482 (GCVE-0-2017-7482)
Vulnerability from cvelistv5 – Published: 2018-07-30 14:00 – Updated: 2024-08-05 16:04
VLAI?
Summary
In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when using the RXRPC keys incorrectly assumes the size of a field. This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. This could possibly lead to memory corruption and possible privilege escalation.

VLAI?
Summary
A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.

CVE-2018-10901 (GCVE-0-2018-10901)
Vulnerability from cvelistv5 – Published: 2018-07-26 17:00 – Updated: 2024-08-05 07:54
VLAI?
Summary
A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges.

CVE-2018-16884 (GCVE-0-2018-16884)
Vulnerability from nvd – Published: 2018-12-18 22:00 – Updated: 2024-08-05 10:32
VLAI?
Summary
A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.
Severity ?

CVE-2018-14646 (GCVE-0-2018-14646)
Vulnerability from nvd – Published: 2018-11-26 19:00 – Updated: 2024-08-05 09:38
VLAI?
Summary
The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service.

CVE-2017-7482 (GCVE-0-2017-7482)
Vulnerability from nvd – Published: 2018-07-30 14:00 – Updated: 2024-08-05 16:04
VLAI?
Summary
In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when using the RXRPC keys incorrectly assumes the size of a field. This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. This could possibly lead to memory corruption and possible privilege escalation.

Vulnerability from nvd – Published: 2018-07-30 13:00 – Updated: 2024-08-05 16:04
VLAI?
Summary
A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.

CVE-2018-10901 (GCVE-0-2018-10901)
Vulnerability from nvd – Published: 2018-07-26 17:00 – Updated: 2024-08-05 07:54
VLAI?
Summary
A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges.
Severity ?
