CVE-2017-18241 in Ubuntu

CVE-2017-18241

Priority

Description

fs/f2fs/segment.c in the Linux kernel before 4.13 allows local users to
cause a denial of service (NULL pointer dereference and panic) by using a
noflush_merge option that triggers a NULL value for a flush_cmd_control
data structure.

Notes

ppisati> fixes a case in the F2FS_FS, when the fs is mounted with the
ppisati> 'noflush_merge' option, but support for flush coalition was introduced in:
ppisati> 6b4afdd794783fe515b50838aa36591e3feea990
tyhicks> The affected user base for this issue is likely small since f2fs is
not the default filesystem and it is not widely used in Ubuntu
