kernel: sound: GPF in snd_seq_fifo_clear

The snd_seq_ioctl_remove_events function in sound/core/seq/seq_clientmgr.c in the Linux kernel before 4.4.1 does not verify FIFO assignment before proceeding with FIFO clearing, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted ioctl call.

kernel: sound: use-after-free in snd_timer_stop

Race condition in the queue_delete function in sound/core/seq/seq_queue.c in the Linux kernel before 4.4.1 allows local users to cause a denial of service (use-after-free and system crash) by making an ioctl call at a certain time.

kernel: sound: use-after-free in snd_timer_interrupt

The snd_timer_interrupt function in sound/core/timer.c in the Linux kernel before 4.4.1 does not properly maintain a certain linked list, which allows local users to cause a denial of service (race condition and system crash) via a crafted ioctl call.

kernel: sound: GPF in snd_timer_user_params

sound/core/timer.c in the Linux kernel before 4.4.1 uses an incorrect type of mutex, which allows local users to cause a denial of service (race condition, use-after-free, and system crash) via a crafted ioctl call.

kernel: sound: use-after-free in snd_timer_user_ioctl

sound/core/timer.c in the Linux kernel before 4.4.1 employs a locking approach that does not consider slave timer instances, which allows local users to cause a denial of service (race condition, use-after-free, and system crash) via a crafted ioctl call.

kernel: sound: linked lists of slave instances not unlinked immediately

sound/core/timer.c in the Linux kernel before 4.4.1 retains certain linked lists after a close or stop action, which allows local users to cause a denial of service (system crash) via a crafted ioctl call, related to the (1) snd_timer_close and (2) _snd_timer_stop functions.

kernel: sound: spinlock lockup in sound/core/timer.c

sound/core/hrtimer.c in the Linux kernel before 4.4.1 does not prevent recursive callback access, which allows local users to cause a denial of service (deadlock) via a crafted ioctl call.

kernel: incorrectly accounted in-flight fds

The Linux kernel before 4.5 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by leveraging incorrect tracking of descriptor ownership and sending each descriptor over a UNIX socket before closing it. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-4312.

kernel: visor: crash on invalid USB device descriptors in treo_attach() in visor driver

The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.

Mozilla: Cairo rendering crash due to memory allocation issue with FFMpeg 0.10 (MFSA 2016-65)

Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 on Linux make cairo _cairo_surface_get_extents calls that do not properly interact with libav header allocation in FFmpeg 0.10, which allows remote attackers to cause a denial of service (application crash) via a crafted video.

kernel: pipe: limit the per-user amount of pages allocated in pipes

fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes.

kernel: aufs module does not properly restrict the mount namespace

The aufs module for the Linux kernel 3.x and 4.x does not properly restrict the mount namespace, which allows local users to gain privileges by mounting an aufs filesystem on top of a FUSE filesystem, and then executing a crafted setuid program.

kernel: aufs module does not properly maintain POSIX ACL xattr data

The aufs module for the Linux kernel 3.x and 4.x does not properly maintain POSIX ACL xattr data, which allows local users to gain privileges by leveraging a group-writable setgid directory.

Stack-based buffer overflow in the ax Shared Libraries in the Agent in IBM Tivoli Monitoring (ITM) 6.2.2 before FP9, 6.2.3 before FP5, and 6.3.0 before FP2 on Linux and UNIX allows local users to gain privileges via unspecified vectors.

kernel: Null pointer dereference in trace_writeback_dirty_page()

The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move.

kernel: netfilter: missing bounds check in ipt_entry structure

The netfilter subsystem in the Linux kernel through 4.5.2 does not validate certain offset fields, which allows local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call.

kernel: netfilter: size overflow in x_tables

Integer overflow in the xt_alloc_table_info function in net/netfilter/x_tables.c in the Linux kernel through 4.5.2 on 32-bit platforms allows local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call.

kernel: Crash on invalid USB device descriptors (mct_u232 driver)

The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device without two interrupt-in endpoint descriptors.

kernel: Crash on invalid USB device descriptors (cypress_m8 driver)

drivers/usb/serial/cypress_m8.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both an interrupt-in and an interrupt-out endpoint descriptor, related to the cypress_generic_port_probe and cypress_open functions.

kernel: Crash on invalid USB device descriptors (cdc_acm driver)

The acm_probe function in drivers/usb/class/cdc-acm.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both a control and a data endpoint descriptor.
