This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU14449
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-5953
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in the swiotlb_print_info() function, as defined in the lib/swiotlb.c source code file due to the printk function prints kernel-object address information. A local attacker can access the system and use a software IO TLB call to read the kernel log.
MitigationUpdate to version 4.14.15.
Vulnerable software versionsLinux kernel: 4.10.0 - 4.14.14
