The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - 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() removed entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry could 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-2018-18445: Faulty computation of numeric bounds in the BPF verifier permitted out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandled 32-bit right shifts (bnc#1112372). - 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-2017-18224: fs/ocfs2/aops.c omitted use of a semaphore and consequently had a race condition for access to the extent tree during read operations in DIRECT mode, which allowed local users to cause a denial of service (BUG) by modifying a certain e_cpos field (bnc#1084831). - 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).
