DATE CVE VULNERABILITY TITLE RISK
2018-04-02 CVE-2018-1095 NULL Pointer Dereference vulnerability in Linux Kernel
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.

5.5
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.

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.

linux CWE-125
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.

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.

2018-03-16 CVE-2018-1068 Out-of-bounds Write vulnerability in multiple products
A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging.

6.7
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.

2018-03-13 CVE-2018-8087 Missing Release of Resource after Effective Lifetime vulnerability in Linux Kernel
Memory leak in the hwsim_new_radio_nl function in drivers/net/wireless/mac80211_hwsim.c in the Linux kernel through 4.15.9 allows local users to cause a denial of service (memory consumption) by triggering an out-of-array error case.

4.9
2018-03-12 CVE-2017-18224 Race Condition vulnerability in Linux Kernel
In the Linux kernel before 4.15, fs/ocfs2/aops.c omits use of a semaphore and consequently has a race condition for access to the extent tree during read operations in DIRECT mode, which allows local users to cause a denial of service (BUG) by modifying a certain e_cpos field.

linux CWE-362
1.9
2018-03-10 CVE-2018-8043 NULL Pointer Dereference vulnerability in Linux Kernel
The unimac_mdio_probe function in drivers/net/phy/mdio-bcm-unimac.c in the Linux kernel through 4.15.8 does not validate certain resource availability, which allows local users to cause a denial of service (NULL pointer dereference).
