DATE CVE VULNERABILITY TITLE RISK
2018-04-02 CVE-2018-1094 NULL Pointer Dereference vulnerability in multiple products
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.

5.5
2018-04-02 CVE-2018-1093 Out-of-bounds Read vulnerability in Linux Kernel
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.

7.1
2018-04-02 CVE-2018-1092 NULL Pointer Dereference vulnerability in Linux Kernel
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.

5.5
2018-03-31 CVE-2017-18255 Integer Overflow or Wraparound vulnerability in Linux Kernel
The perf_cpu_time_max_percent_handler function in kernel/events/core.c in the Linux kernel before 4.11 allows local users to cause a denial of service (integer overflow) or possibly have unspecified other impact via a large value, as demonstrated by an incorrect sample-rate calculation.

4.6
2018-03-27 CVE-2018-1091 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Linux Kernel
In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c in the Linux kernel before 4.13.5, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory (TM) instructions in the core dump path, leading to a denial of service.

linux CWE-119
4.9
2018-03-26 CVE-2017-18249 Race Condition vulnerability in Linux Kernel
The add_free_nid function in fs/f2fs/node.c in the Linux kernel before 4.12 does not properly track an allocated nid, which allows local users to cause a denial of service (race condition) or possibly have unspecified other impact via concurrent threads.
4.4
2018-03-21 CVE-2017-18241 NULL Pointer Dereference vulnerability in Linux Kernel
fs/f2fs/segment.c in the Linux kernel before 4.13 allows local users to cause a denial of service (NULL pointer dereference and panic) by using a noflush_merge option that triggers a NULL value for a flush_cmd_control data structure.

4.9
2018-03-20 CVE-2018-8822 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Incorrect buffer length handling in the ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c in the Linux kernel through 4.15.11, and in drivers/staging/ncpfs/ncplib_kernel.c in the Linux kernel 4.16-rc through 4.16-rc6, could be exploited by malicious NCPFS servers to crash the kernel or execute code.

2018-03-15 CVE-2017-18232 Unspecified vulnerability in Linux Kernel
The Serial Attached SCSI (SAS) implementation in the Linux kernel through 4.15.9 mishandles a mutex within libsas, which allows local users to cause a denial of service (deadlock) by triggering certain error-handling code.
