CVE-2019-13104
In Das U-Boot versions 2016.11-rc1 through 2019.07-rc4, an underflow can cause memcpy() to overwrite a very large amount of data (including the whole stack) while reading a crafted ext4 filesystem.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.12%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
