CVE-2025-70100
A divide-by-zero vulnerability in the ext4blocksetlbsize function in src/ext4blockdev.c of the lwext4 1.0.0 library allows attackers to cause a denial of service by providing a malformed ext4 filesystem image that results in a zero logical block size. The vulnerability is triggered during mount o...
CVE-2025-70100
CVE-2025-70100 affects lwext4 1.0.0. A divide-by-zero in ext4_block_set_lb_size (src/ext4_blockdev.c) can cause denial of service when processing a malformed ext4 image, triggering a Floating-Point Exception or crash due to missing lb_size validation during mount/image handling. Connected sources...
