An unprivileged, local user could use this flaw to crash the system or, potentially (although highly unlikely), escalate their privileges on the system.(CVE-2015-5157) - A denial of service vulnerability was found in the WhiteHEAT USB Serial Driver (whiteheat_attach function in drivers/usb/serial/whiteheat.c). In the driver, the COMMAND_PORT variable was hard coded and set to 4 (5th element). The driver assumed that the number of ports would always be 5 and used port number 5 as the command port. However, when using a USB device in which the number of ports was set to a number less than 5 (for example, 3), the driver triggered a kernel NULL-pointer dereference. A non-privileged attacker could use this flaw to panic the host.(CVE-2015-5257) - A NULL pointer dereference flaw was found in the SCTP implementation. A local user could use this flaw to cause a denial of service on the system by triggering a kernel panic when creating multiple sockets in parallel while the system did not have the SCTP module loaded.(CVE-2015-5283) - It was found that the x86 ISA (Instruction Set Architecture) is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way (sequential) delivering of benign exceptions such as #AC (alignment check exception) is handled.

The following security bugs were fixed : - CVE-2015-1339: A memory leak in cuse could be used to exhaust kernel memory. (bsc#969356). - CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel did not ensure that certain slot numbers are valid, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call (bnc#949936 951638). - CVE-2015-7872: The key_gc_unused_keys function in security/keys/gc.c in the Linux kernel allowed local users to cause a denial of service (OOPS) via crafted keyctl commands (bnc#951440). - CVE-2015-7884: The vivid_fb_ioctl function in drivers/media/platform/vivid/vivid-osd.c in the Linux kernel did not initialize a certain structure member, which allowed local users to obtain sensitive information from kernel memory via a crafted application (bnc#951626). - CVE-2015-8104: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c (bnc#954404). - CVE-2015-8709: kernel/ptrace.c in the Linux kernel mishandled uid and gid mappings, which allowed local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call.

It is, therefore, affected by the following vulnerabilities : - A use-after-free error exists in the unix_dgram_poll() function within file net/unix/af_unix.c. A local attacker can exploit this, via specially crafted epoll_ctl calls, to cause a denial of service condition or bypass AF_UNIX socket permissions. (CVE-2013-7446) - A NULL pointer dereference flaw exists in the slhc_init() function within file drivers/net/slip/slhc.c due to improper validation of slot numbers. A local attacker can exploit this, via specially crafted PPPIOCSMAXCID IOCTL calls, to cause a denial of service condition. (CVE-2015-7799) - A flaw exists in the usbvision driver that allows a local attacker, via a nonzero bInterfaceNumber value in a USB device descriptor, to cause a kernel panic, resulting in a denial of service condition. (CVE-2015-7833) - An infinite loop condition exists in the KVM subsystem on some unspecified CPU chipsets. A local attacker who has sufficient privileges within a virtual guest OS can exploit this issue, by triggering many debug exceptions, to cause a denial of service condition. (CVE-2015-8104) - A flaw exists in the truncate_space_check() function within file /fs/btrfs/inode.c due to improper handling of compressed file extents. A local attacker can exploit this, via a clone action, to disclose sensitive pre-truncation information from a file. (CVE-2015-8374) - A NULL pointer dereference flaw exists in the inet_autobind() function within file net/ipv4/af_inet.c when handling connection attempts via IPv6. A local attacker can exploit this, via a specially crafted SOCK_RAW application that makes use of CLONE_NEWUSER support, to cause a denial of service condition or possibly gain elevated privileges.
