CVE-2014-4652

Status Candidate

Overview

Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.

Red Hat Security Advisory 2015-1272-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way Linux kernel's Transparent Huge Pages implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. A buffer overflow flaw was found in the way the Linux kernel's eCryptfs implementation decoded encrypted file names. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.

Red Hat Security Advisory 2014-1971-01 - A flaw was found in the way the Linux kernel's SCTP implementation handled malformed or duplicate Address Configuration Change Chunks. A remote attacker could use either of these flaws to crash the system. A flaw was found in the way the Linux kernel's SCTP implementation handled the association's output queue. A remote attacker could send specially crafted packets that would cause the system to use an excessive amount of memory, leading to a denial of service.

Ubuntu Security Notice 2337-1 - A flaw was discovered in the Linux kernel virtual machine's (kvm) validation of interrupt requests (irq). A guest OS user could exploit this flaw to cause a denial of service (host OS crash). Andy Lutomirski discovered a flaw in the authorization of netlink socket operations when a socket is passed to a process of more privilege. A local user could exploit this flaw to bypass access restrictions by having a privileged executable do something it was not intended to do. Various other issues were also addressed.

Ubuntu Security Notice 2335-1 - An flaw was discovered in the Linux kernel's audit subsystem when auditing certain syscalls. A local attacker could exploit this flaw to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS). An information leak was discovered in the rd_mcp backend of the iSCSI target subsystem in the Linux kernel. A local user could exploit this flaw to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator. Various other issues were also addressed.
