The SUSE Linux Enterprise 11 SP4 RT kernel was updated to 3.0.101-rt130-69.39 to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-18281: An issue was discovered in the Linux kernel, 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 issue was discovered in the Linux kernel, 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 in the Linux kernel 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 in the Linux kernel 4.x 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 in the Linux kernel 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: An denial of service issue was discovered in the Linux kernel, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021).
- CVE-2018-9516: An issue was discovered in the Linux kernel, the copy_to_user() inside the HID code does not...
