CVE-2019-19319
Last modified
CVE-2019-19319 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call, aka CID-345c0dbf3a30.. EPSS estimates a 0.69% chance of exploitation in the next 30 days.
