| Title | Divide‑by‑Zero in lwext4 Ext4 Block Size Validation Leading to DoS | |
| Weaknesses | CWE-369 |
| Type | Values Removed | Values Added |
|---|---|---|
| Description | A divide-by-zero vulnerability in the ext4_block_set_lb_size function in src/ext4_blockdev.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 or image processing and leads to a Floating-Point Exception (FPE) under sanitizers or a runtime crash in standard builds due to missing validation of lb_size. | |
