"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix kernel BUG in ext4_write_inline_data_end\n\nWhen the data=journal mount option is used, the ext4_journalled_write_end()\nfunction incorrectly calls ext4_write_inline_data_end() without checking\nif the EXT4_STATE_MAY_INLINE_DATA flag is still set on the inode.\n\nIf a previous attempt to convert the inline data to an extent failed (e.g.\ndue to ENOSPC), the EXT4_STATE_MAY_INLINE_DATA flag is cleared, but\nthe EXT4_INODE_INLINE_DATA flag remains set. In this scenario, the next\ncall to ext4_write_begin() will not prepare the inline data xattr for\nwriting, but ext4_journalled_write_end() will incorrectly attempt to write\nto it, triggering a BUG_ON(pos + len > EXT4_I(inode)->i_inline_size) in\next4_write_inline_data() since i_inline_size was not expanded.\n\nFix this by ensuring that ext4_journalled_write_end() only calls\next4_write_inline_data_end() if the EXT4_STATE_MAY_INLINE_DATA flag is\nset, mirroring the behavior of ext4_write_end() and ext4_da_write_end()."
