CVE-2025-38627

CVE-2025-38627 affects the f2fs component of the Linux kernel. The root cause is a use-after-free of f2fs_inode_info in f2fs_free_dic when decompress_io_ctx is released asynchronously after I/O completion, potentially evicting the inode before dic is used. The exploit scenario involves concurrent...
