CVE-ID: CVE-2018-11412

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local attacker to gain elevated privileges or cause DoS condition on the target system.

The vulnerability exists due to improper memory operations performed by the ext4_read_inline_data() function, as defined in the fs/ext4/inline.c source code file. A local attacker can mount a customized ext4 filesystem that stores the system.data extended attribute value in a dedicated inode, supply malicious input containing an untrusted length value, trigger memory corruption and gain elevated privileges or cause a DoS condition.

Mitigation

Install updates from vendor's repository.
