2) NULL pointer dereference
EUVDB-ID: #VU11518
Risk: Low
CVSSv4.0: 5.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2018-1092
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists due to improper processing of a customized ext4 image when using the ext4_iget function, as defined in the fs/ext4/inode.c source code file. A local attacker can mount a customized ext4 image, trigger NULL pointer dereference and an Out-of-Process Space (OOPS) kernel memory error and cause the service to crash.
Update the affected package Slackware 14.2 kernel.
Vulnerable software versionsSlackware Linux: 14.2
