CVE-2014-7975

Status Candidate

Overview

The do_umount function in fs/namespace.c in the Linux kernel through 3.17 does not require the CAP_SYS_ADMIN capability for do_remount_sb calls that change the root filesystem to read-only, which allows local users to cause a denial of service (loss of writability) by making certain unshare system calls, clearing the / MNT_LOCKED flag, and making an MNT_FORCE umount system call.

Red Hat Security Advisory 2017-1842-01
Posted Aug 2, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-1842-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A local user could use this flaw to crash the system or, potentially, escalate their privileges.

Red Hat Security Advisory 2017-2077-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A local user could use this flaw to crash the system or, potentially, escalate their privileges.

Ubuntu Security Notice 2417-1 - Nadav Amit reported that the KVM (Kernel Virtual Machine) mishandles noncanonical addresses when emulating instructions that change the rip (Instruction Pointer). A guest user with access to I/O or the MMIO can use this flaw to cause a denial of service (system crash) of the guest. A flaw was discovered with the handling of the invept instruction in the KVM (Kernel Virtual Machine) subsystem of the Linux kernel. An unprivileged guest user could exploit this flaw to cause a denial of service (system crash) on the guest. Various other issues were also addressed.

Ubuntu Security Notice 2421-1 - A flaw was discovered in how the Linux kernel's KVM (Kernel Virtual Machine) subsystem handles the CR4 control register at VM entry on Intel processors. A local host OS user can exploit this to cause a denial of service (kill arbitrary processes, or system disruption) by leveraging /dev/kvm access. Don Bailey discovered a flaw in the LZO decompress algorithm used by the Linux kernel. An attacker could exploit this flaw to cause a denial of service (memory corruption or OOPS). Various other issues were also addressed.
