CVE-2018-1093

Updated: 2023-11-24

CWE: Out-of-bounds Read

Description:

The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image because balloc.c and ialloc.c do not validate bitmap block numbers.

CVSS3: 5.5
