Description:


The SUSE Linux Enterprise 12 SP3 kernel was updated to 3.0.101 to receive various security and bugfixes.
The following security bugs were fixed:

  • CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1108498).
  • CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841).
  • CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bnc#1120743).
  • CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714).
  • CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation (bnc#1118319).
  • CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).
  • CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused (bnc#1113769).
  • CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751).
  • CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825).
  • CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240).
  • CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674).
  • CVE-2017-1000407: Fixed a denial of service, which was caused by flooding the diagnostic port 0x80 an exception leading to a kernel panic (bnc#1071021).
