CVE-ID: CVE-2019-11811
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local usre to elevate privileges on the system.
The vulnerability exists due to a use-after-free error when trying to read data from /proc/ioports after the ipmi_si module is removed (related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c). A local user can exploit this issue to elevate privileges on the system.

EUVDB-ID: #VU16896
Risk: Low
CVSSv4.0: 5.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2019-5489
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain access to potentially sensitive information.
The vulnerability exists due to a flaw in the mincore() implementation in mm/mincore.c. A local attacker can observe page cache access patterns of other processes on the same system and sniff secret information.

CVE-ID: CVE-2017-18208
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists in the madvise_willneed function due to infinite loop. A local attacker can trigger use of MADVISE_WILLNEED for a DAX mapping and cause the service to crash.

CVE-ID: CVE-2019-3900
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in vhost_net kernel module when processing incoming packets in handle_rx(). A remote attacker with access to guest operating system can stall the vhost_net kernel thread and cause denial of service conditions.

CVE-ID: CVE-2017-10661
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to gain elevated privileges or cause DoS condition on the target system.
The weakness exists due to race condition in fs/timerfd.c in the Linux kernel. A local attacker can use simultaneous file-descriptor operations, leverage improper might_cancel queueing, trigger list corruption or use-after-free and cause the service to crash or execute arbitrary code with root privileges.
