CVE-2019-19449

HIGH7.8

In the Linux kernel 5

Published Dec 8, 2019

Modified 1 years ago

Details

In the Linux kernel 5.0.21, mounting a crafted f2fs filesystem image can lead to slab-out-of-bounds read access in f2fs_build_segment_manager in fs/f2fs/segment.c, related to init_min_max_mtime in fs/f2fs/segment.c (because the second argument to get_seg_entry is not validated).
