The following security bugs were fixed:
- CVE-2018-3665: Prevent disclosure of FPU registers (including XMM and
AVX registers) between processes. These registers might contain
encryption keys when doing SSE accelerated AES enc/decryption
(bsc#1087086)
- CVE-2018-5848: In the function wmi_set_ie(), the length validation code
did not handle unsigned integer overflow properly. As a result, a large
value of the 'ie_len' argument could have caused a buffer overflow
(bnc#1097356)
- CVE-2018-1000204: Prevent infoleak caused by incorrect handling of the
SG_IO ioctl (bsc#1096728)
- CVE-2017-13305: Prevent information disclosure vulnerability in
encrypted-keys (bsc#1094353)
- CVE-2018-1094: The ext4_fill_super function did not always initialize
the crc32c checksum driver, which allowed attackers to cause a denial of
service (ext4_xattr_inode_hash NULL pointer dereference and system
crash) via a crafted ext4 image (bsc#1087007).
- CVE-2018-1093: The ext4_valid_block_bitmap function allowed 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 (bsc#1087095).
- CVE-2018-1092: The ext4_iget function mishandled the case of a root
directory with a zero i_links_count, which allowed attackers to cause a
denial of service (ext4_process_freed_data NULL pointer dereference and
OOPS) via a crafted ext4 image (bsc#1087012).
- CVE-2018-1130: NULL pointer dereference in dccp_write_xmit() function
that allowed a local user to cause a denial of service by a number of
certain crafted system calls (bsc#1092904)
- CVE-2018-5803: Prevent error in the '_sctp_make_chunk()' function when
handling SCTP packets length that could have been exploited to cause a
kernel crash (bnc#1083900)
- CVE-2018-7492: Prevent NULL pointer dereference in the net/rds/rdma.c
__rds_rdma_map() function that allowed local attackers to cause a system
panic and a denial-of-service, related to RDS_GET_MR and
RDS_GET_MR_FOR_DEST (bsc#1082962)
The following non-security bugs were fixed:
- Btrfs: fix unexpected balance crash due to BUG_ON (bsc#1038553).
- Fix excessive newline in /proc/*/status (bsc#1094823).
- KVM: x86: Sync back MSR_IA32_SPEC_CTRL to VCPU data structure
(bsc#1096242, bsc#1096281).
- dm thin metadata: call precommit before saving the roots (bsc#1083382).
- dm thin: fix inability to discard blocks when in out-of-data-space mode
(bsc#1083382).
- dm thin: fix missing out-of-data-space to write mode transition if
blocks are released (bsc#1083382).
- dm thin: restore requested 'error_if_no_space' setting on OODS to WRITE
transition (bsc#1083382).
- dm: fix various targets to dm_register_target after module __init
resources created (bsc#1083382).
- kABI: work around BPF SSBD removal ... [Please see the references for more information on the vulnerabilities]");
