CVE-2019-19814
In the Linux kernel 5.0.21, mounting a crafted f2fs filesystem image can cause __remove_dirty_segment slab-out-of-bounds write access because an array is bounded by the number of dirty types (8) but the array index can exceed this.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
