DATE CVE VULNERABILITY TITLE RISK
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.

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).

linux canonical CWE-476
2.1
2018-03-09 CVE-2018-7995 Race Condition vulnerability in multiple products
Race condition in the store_int_with_restart() function in arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel through 4.15.7 allows local users to cause a denial of service (panic) by leveraging root access to write to the check_interval file in a /sys/devices/system/machinecheck/machinecheck<cpu number> directory.

linux canonical debian CWE-362
4.7
2018-03-08 CVE-2018-7757 Missing Release of Resource after Effective Lifetime vulnerability in Linux Kernel
Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux kernel through 4.15.7 allows local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sas_phy directory, as demonstrated by the /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file.

linux CWE-772
2.1
2018-03-08 CVE-2018-7755 Information Exposure vulnerability in Linux Kernel
An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7.

2.1
2018-03-07 CVE-2018-7740 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Linux Kernel
The resv_map_release function in mm/hugetlb.c in the Linux kernel through 4.15.7 allows local users to cause a denial of service (BUG) via a crafted application that makes mmap system calls and has a large pgoff argument to the remap_file_pages system call.

linux redhat canonical debian CWE-119
4.9
2018-03-05 CVE-2017-18218 Use After Free vulnerability in Linux Kernel
In drivers/net/ethernet/hisilicon/hns/hns_enet.c in the Linux kernel before 4.13, local users can cause a denial of service (use-after-free and BUG) or possibly have unspecified other impact by leveraging differences in skb handling between hns_nic_net_xmit_hw and hns_nic_net_xmit.

linux CWE-416
7.8
2018-03-05 CVE-2017-18216 NULL Pointer Dereference vulnerability in Linux Kernel
In fs/ocfs2/cluster/nodemanager.c in the Linux kernel before 4.15, local users can cause a denial of service (NULL pointer dereference and BUG) because a required mutex is not used.

linux CWE-476
2.1
2018-03-02 CVE-2018-1065 NULL Pointer Dereference vulnerability in Linux Kernel
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.

2018-03-01 CVE-2017-18208 Infinite Loop vulnerability in Linux Kernel
The madvise_willneed function in mm/madvise.c in the Linux kernel before 4.14.4 allows local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping.
