CVE-2025-38222

Summary : CVE-2025-38222 refers to a Linux kernel vulnerability in ext4 inline data handling. When inline_data is enabled, a length parameter (len) is incorrectly treated as an unsigned int, causing a truncation of pos+len in ext4_prepare_inline_data. This leads to an incorrect len being passed t...
