CVE-2018-1068

A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory.

This kernel update is based on the upstream 4.14.30 and fixes at least the following security issues:

The KPTI mitigation for Meltdown (CVE-2017-5754) on 32bit x86 has been updated to revision 4.

A flaw was found in the Linux kernel implementation of 32 bit syscall interface for bridging allowing a privileged user to arbitrarily write to a limited range of kernel memory. This flaw can be exploited not only by a system's privileged user (a real "root" user), but also by an attacker who is a privileged user (a "root" user) in a user+network namespace (CVE-2018-1068).

A race condition vulnerability exists in the sound system, that can lead to a deadlock and denial of service condition (CVE-2018-1000004).

Other changes in this update:

3rdparty rtl8812au driver has been updated to v5.2.20 (mga#22808) and adds fixes for KRACK security issue.

This kernel-tmb update is based on the upstream 4.14.44 and fixes at least the following security issues:

This update adds KPTI mitigation for Meltdown (CVE-2017-5754) on 32bit x86.

The netfilter subsystem in the Linux kernel through 4.15.7 mishandles the case of a rule blob that contains a jump but lacks a user-defined chain, which allows local users to cause a denial of service (NULL pointer dereference) by leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability, related to arpt_do_table in net/ipv4/netfilter/arp_tables.c, ipt_do_table in net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in net/ipv6/netfilter/ip6_tables.c (CVE-2018-1065).

A flaw was found in the Linux kernel implementation of 32 bit syscall interface for bridging allowing a privileged user to arbitrarily write to a limited range of kernel memory. This flaw can be exploited not only by a system's privileged user (a real "root" user), but also by an attacker who is a privileged user (a "root" user) in a user+network namespace (CVE-2018-1068).

On x86, MOV SS and POP SS behave strangely if they encounter a data breakpoint. If this occurs in a KVM guest, KVM incorrectly thinks that a #DB instruction was caused by the undocumented ICEBP instruction. This results in #DB being delivered to the guest kernel with an incorrect RIP on the stack. On most guest kernels, this will allow a guest user to DoS the guest kernel or even to escalate privilege to that of the guest kernel (CVE-2018-1087).

The ext4_iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a root directory with a zero i_links_count, which allows attackers to cause a denial of service (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4 image (CVE-2018-1092).

The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image because balloc.c and ialloc.c do not validate bitmap block numbers (CVE-2018-1093).

The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted ext4 image (CVE-2018-1094).

The ext4_xattr_check_entries function in fs/ext4/xattr.c in the Linux kernel through 4.15.15 does not properly validate xattr sizes, which causes misinterpretation of a size as an error code, and consequently allows attackers to cause a denial of service (get_acl NULL pointer dereference and system crash) via a crafted ext4 image (CVE-2018-1095).

By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks) (CVE-2018-1120).

A null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in the Linux kernel before v4.16-rc7 allows a local user to cause a denial of service by a number of certain crafted system calls (CVE-2018-1130).

Speculative Store Bypass (SSB) – also known as Spectre Variant 4. Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis (CVE-2018-3639). NOTE! This fix only apply to Amd hardware so far as Intel CPUs need a fixed microcode update in order for the fix to get activated. At the time of this release we dont yet know when Intel will release new microcode.
