The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.156 to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-16597: Incorrect access checking in overlayfs mounts could have been used by local attackers to modify or truncate files in the underlying filesystem (bnc#1106512). - CVE-2018-14613: Prevent invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, caused by a lack of block group item validation in check_leaf_item (bsc#1102896) - CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870) - CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in yurex_read allowed local attackers to use user access read/writes to crash the kernel or potentially escalate privileges (bsc#1106095) - CVE-2018-7757: Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c allowed local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sas_phy directory, as demonstrated by the /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file (bnc#1084536) - CVE-2018-7480: The blkcg_init_queue function allowed local users to cause a denial of service (double free) or possibly have unspecified other impact by triggering a creation failure (bsc#1082863). - CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bnc#1108399).
