Description
The vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to NULL pointer dereference in the __remove_dirty_segment() function, as defined in the source code file fs/f2fs/inode.c when mounting Flash-Friendly File System (F2FS) images. A local attacker can mount a specially crafted F2FS filesystem that submits malicious input and cause the affected software to terminate abnormally.
Remediation
Update to version 4.17.11.
