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.

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.

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.

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.

A local user could exploit this flaw to cause a denial of service (system crash) via an open system call. Toralf reported an error in the Linux kernels syscall auditing on 32 bit x86 platforms. A local user could exploit this flaw to cause a denial of service (OOPS and system crash). An information leak was discovered in the control implementation of the Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. A local user could exploit this flaw to obtain sensitive information from kernel memory. Various other issues were also addressed.

A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. Multiple use-after-free flaws and an integer overflow flaw were found in the way the Linux kernel's Advanced Linux Sound Architecture implementation handled user controls. A local, privileged user could use either of these flaws to crash the system.
