Summary
Security update for the Linux Kernel
Details

The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2018-14634: Prevent integer overflow in createelftables that allowed a local attacker to exploit this vulnerability via a SUID-root binary and obtain full root privileges (bsc#1108912)
  • 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-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INTMAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timergetoverrun(2) and siginfo::sioverrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timercreate, and timer_settime system calls (bnc#1099922)
  • CVE-2018-13093: Prevent NULL pointer dereference and panic in lookupslow() on a NULL inode->iops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001)
  • CVE-2018-10940: The cdromioctlmediachanged function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROMMEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)
  • CVE-2018-16658: Prevent information leak in cdromioctldrive_status that could have been used by local attackers to read kernel memory (bnc#1107689)
  • CVE-2018-6555: The irdasetsockopt function allowed local users to cause a denial of service (iasobject use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511)
  • CVE-2018-6554: Prevent memory leak in the irdabind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AFIRDA socket (bnc#1106509)
  • CVE-2018-10853: The KVM hypervisor did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could have used this flaw to potentially escalate privileges inside guest (bsc#1097104)
  • CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in sndrawmidiinputparams() and sndrawmidioutputstatus(). A malicious local attacker could have used this for privilege escalation (bnc#1105322).
  • CVE-2018-10879: A local user could have caused a use-after-free in ext4xattrset_entry function and a denial of service or unspecified other impact by renaming a file in a crafted ext4 filesystem image (bsc#1099844)
  • CVE-2018-10883: A local user could have caused an out-of-bounds write in jbd2journaldirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099863)
  • CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4updateinline_data(). An attacker could have used this to cause a system crash and a denial of service (bsc#1099845)
  • CVE-2018-10882: A local user could have caused an out-of-bound write, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image (bsc#1099849)
  • CVE-2018-10881: A local user could have caused an out-of-bound access in ext4getgroup_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099864)
  • CVE-2018-10877: Prevent out-of-bound access in the ext4extdrop_refs() function when operating on a crafted ext4 filesystem image (bsc#1099846)
  • CVE-2018-10876: A use-after-free was possible in ext4extremove_space() function when mounting and operating a crafted ext4 image (bsc#1099811)
  • CVE-2018-10878: A local user could have caused an out-of-bounds write and a denial of service or unspecified other impact by mounting and operating a crafted ext4 filesystem image (bsc#1099813)
  • CVE-2018-17182: An issue was discovered in the Linux kernel The vmacacheflushall 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).

The following non-security bugs were fixed:

  • bcache: avoid unncessary cache prefetch bchbtreenode_get().
  • bcache: calculate the number of incremental GC nodes according to the total of btree nodes.
  • bcache: display rate debug parameters to 0 when writeback is not running.
  • bcache: do not check return value of debugfscreatedir().
  • bcache: finish incremental GC.
  • bcache: fix error setting writeback_rate through sysfs interface (bsc#1064232).
  • bcache: fix I/O significant decline while backend devices registering.
  • bcache: free heap cacheset->flushbtree in bchjournalfree.
  • bcache: make the prerr statement used for ENOENT only in sysfsattatch section.
  • bcache: release dc->writebacklock properly in bchwriteback_thread().
  • bcache: set max writeback rate when I/O request is idle (bsc#1064232).
  • bcache: simplify the calculation of the total amount of flash dirty data.
  • Do not report CPU affected by L1TF when ARCHCAPRDCL_NO bit is set (bsc#1104906).
  • ext4: check for allocation block validity with block group locked (bsc#1104495).
  • ext4: do not update checksum of new initialized bitmaps (bnc#1012382).
  • ext4: fix check to prevent initializing reserved inodes (bsc#1104319).
  • ext4: fix false negatives and false positives in ext4checkdescriptors() (bsc#1103445).
  • kABI: protect struct x86emulateops (kabi).
  • KEYS: prevent creating a different user's keyrings (bnc#1065999).
  • KVM: MMU: always terminate page walks at level 1 (bsc#1062604).
  • KVM: MMU: simplify lastptebitmap (bsc#1062604).
  • KVM: nVMX: update lastnonleaflevel when initializing nested EPT (bsc#1062604).
  • KVM: VMX: fixes for vmentryl1dflush module parameter (bsc#1106369).
  • KVM: VMX: Work around kABI breakage in 'enum vmxl1dflush_state' (bsc#1106369).
  • updated sssbd handling (bsc#1093215, bsc#1105412).
  • usbip: vhci_sysfs: fix potential Spectre v1 (bsc#1096547).
  • x86/speculation: Use ARCH_CAPABILITIES to skip L1D flush on vmentry (bsc#1106369).
  • sched/sysctl: Check user input value of sysctlschedtime_avg (bsc#1100089).
